In the fall of 2022 CityClimate meets CreativeCoding brought together international artists, data analysts and data curators to work on new data art projects. The basis for these were the digital tools developed at the City Science Lab at the HafenCity University Hamburg. After a year of collaborative exploration, the three day festival presents three projects developed at City Science Lab alongside a selection of current media art, workshops, films, and projects developed at the Centre for Urban Science & Policy @ Delft University of Technology. 

City Science Lab investigates the urban challenges in the era of digitalization in cooperation with partners from civil society, politics, economy, and science. It pursues an inter- and transdisciplinary perspective by linking technical issues with social and cultural developments. As part of their work the City Science Lab develops digital city models based on comprehensive urban data to make future cities more sustainable.

Opening Panel

Jupiter, 3rd floor
Wed. 04.10.2023, 16:00-16:30

Complex challenges need collaborative action. Man made climate change challenges established divisions and professional certitudes. CityClimate meets CreativeCoding started over a year ago by inviting collaborations on a cross-professional and international scale. For the Festival we have sought another collaboration with the Centre for Urban Science and Policy at Delft University of Technology. In the opening panel we discuss what can happen at the intersection of art and science in a time of crisis, what expectations we have and what challenges we face and why transdisciplinary research is crucial for urban transformation in the face of the climate crisis.

What if city planning was automated according to local climate data? What if urban development prioritized trees over cars and the health of the ecosystem over human comfort and the economy? How would city planning change if we relinquished control to non-human actors? What trade-offs and compromises will we have to make in the face of the climate crisis?

The City Robot Lab HIATUS team have considered these questions and implemented a unique and radical proposal. The HIATUS robots move autonomously through Hamburg planting trees wherever they find urban heat islands, re-greening the city.

Waking the Giants (2022)

Lecture Performance

Jupiter, 3rd floor
Wed. 04.10.2023, from 19:00-20:00

Waking the Giants was developed by Egyptian visual artist Aya Tarek and Swiss musician Simon Petermann as a multimedia installation exhibition in Cairo in 2022 to accompany the UN-Climate Conference COP 27. For CityClimate meets CreativeCoding Festival the artists have developed a lecture performance based on the original exhibition.

Egyptian visual artist Aya Tarek and Swiss musician Simon Petermann present their own artistic perception of climate change by a melodic translation of data collected from the Institute for Atmospheric and Climate Science in Zurich, accompanied by an interweaving visual portrayal of flashes from societal collective perception of the apocalypse, transporting their audience to a reality whose formulation is no longer discreet. 'Waking the Giants is the envisioning of a reality concocted by scientific graphs and charts, a sneak peek on an alarming future in the making.

Thu. 05.10.2023, 10:00-13:00
Online reservation required!

Autonomous urban robots are starting to appear in European cities, with delivery-, scanning-, cleaning-, advertising-, security-, or waiter- robots being just some examples. Current development of most such robots is driven by commercial interests, with limited consideration for their impact on cities, communities, and ecosystems. In the Cities of Things Lab 010 (, we take a different approach by treating urban robots as future co-citizens and advocating for their integration into democratic society and local civic communities. We've created a low-cost kit ( for co-prototyping neighborhood robots with input from citizens. Resulting prototypes show how robots can become part of and contribute to local communities. In the workshop, we will prototype climate-focused neighborhood bots for Hamburg's streets. We will explore the opportunities and risks posed by robotics developments in our cities, communities and ecosystems, and we will investigate how such robots can become enablers of bottom-up systemic change.

Data Mural Workshop


Jupiter, 3rd floor

Thu. 05.10.2023, 13:30-15:30
Online reservation required!

Over 9% of the total area in Hamburg is designated as nature reserves. None of the wind turbines in Hamburg are located north of the river Elbe. Approximately 240 different beetle species inhabit the green roofs of the city. The non-material waste from the refuse of Hamburg's 1.8 million residents is incinerated 100% in two waste-to-energy plants and not deposited in landfills. Various data of the Hanseatic city can be accessed through the Urban Data Hub and other open data portals.

In this workshop, the Hamburg-based urban art artist Tasek, along with the participants, creates a data mural: Various data from the city of Hamburg are related to a design and implemented in the workshop using typical tools from urban art forms.

 At the end of the workshop, an image will aesthetically represent the data of the city of Hamburg.

Thu. 05.10.2023, 17:00-18:00
Online reservation required!

We are looking for the Urban Digitope! What does it look like? Big, small; ex- or inclusive, stingy or generous?

The Urban Digitope is a game between digital and physical space of the city. An inexhaustible source of urban processes. The game narrates the climate crisis and its possible results in cities. Its aim is to raise awareness for such challenges and create collaborative practices to find solutions by learning to switch perspectives, discuss beyond your discipline and find consensus through practice.

Citizen AI explores a possible near future, where the climate politics of Hamburg is transferred to a citizen council advised by scientists, an AI and a system dynamics model. Governments worldwide have prioritized the short-term gain of industry and capital at the expense of environmental health and the survival of countless species – could an AI and a scientifically informed citizen councilset new standards for a humanist politics?

The work consists of an intervention in public space with a poster campaign claiming that an AI will take over Hamburg's climate policy and a performative installation where visitors can discuss proposed measures against climate change, select a set of measures and evaluate their effectiveness. The project is a provocation, an experiment and a search for a way to deal with the massive failure of human politicians in responsible climate policy.


Thu. 05.10.2023, 15:00-17:00

In addition, on the second festival day Mikala Hyldig will invite audiences to engage in conversation with the ECO-ORACLE, an AI persona driven by a deep commitment to the preservation of our planet.

Asunder responds to a growing interest in the application of AI to critical environmental challenges by situating this approach as a literal proposition, combining state of the art climate and environmental simulation technology, a 144 CPU super-computer and Machine Learning image-making techniques. The result is a fictional 'environmental manager' that proposes and simulates future alterations to the planet to keep it safely within planetary boundaries, with what are often completely unacceptable or absurd results. In doing so, Asunder questions assumptions of computational neutrality, our increasingly desperate reach for techno-solutionist fixes to planetary challenges, and the broader ideological framing of the environment as a system. 


For CityClimate meets CreativeCoding Festival the artists have combined the original three channel video into a single projection.

By the year 2070, parts of Rotterdam will experience frequent flooding caused by rising sea levels and intense heavy rainfall events. This hands-on exhibit presents the dilemmas of people living in a Rotterdam neighborhood who are grappling with an uncertain future for their community. Through the use of embedded AI, we show how participation can be done in the future to include values and local knowledge in urban planning and decision making. The installation aims to highlight the flow of citizen-generated data from neighborhood buzz into a high-stakes municipal board room. The installation consists of three experimental devices, each demonstrating novel forms of collection and use of citizen input in a city planning process.


The participAIte project was developed by Delft University of Technology Masters students in the Interactive Technology Design course. It serves as an extension of Citizen Voice, an open-source platform for public participation and citizen engagement that aims to ensure all voices are heard in decisions that shape the future of cities.

Multispecies Society Hamburg

Organism Democracy Workshop

Jupiter and surroundings
Start: Jupiter entrance

Thu. 05.10.2023, 11:00-13:00
Online reservation required!

Organisms Democracy is a model project currently running in three cities to bring all species together on equal terms within a political system. During the workshop, methods and techniques of practicing empathy, representing and debating in the name of more-than-human species will be offered, discussed and tried out by the participants of the workshop. Issues of urban development, globalization and climate crisis will be addressed from more-than-human perspectives.

Is there a way to imagine a city of which all living beings are equal citizens? By what right have more-than-human city dwellers been deprived of any civil rights so far? And what kind of results has this exclusion generated in terms of quality and resilience of the city ecosystem? What would change in urban planning and in everyday urban life if the Chinese Mitten Crab, the White Poplar and the Mud Dauber Wasp were allowed to have a say in how the ecosystem of Hamburg should evolve? How could it work to make the realities and needs of other living beings part of the political process?

Thu. 05.10.2023 16:00-17:00
Online reservation required!

With city temperatures reaching upwards of 70C, we are cooking our cities well done (CNN, 2023). Dealing with intensifying heat in our cities requires broad participation and solutions must be evidence-based. From designing methods for citizen engagement (metaplanning) to co-creating interventions for cool streetscapes (microplanning), experience how the principles of mixing-and-matching, gamification, co-creation and scientific knowledge come together to make the planning of resilient urban cities and spaces more feasible, desirable and engaging.

Game On for Sustainable Cities: Powering Research through Serious Gaming

Panel Talk

Jupiter, 5th floor

Thu. 05.10.2023, 18:00-18:30

Humans are playful creatures. All the basics that we’ve learned to live, thrive and grow as individual beings we gained through play. There is simply no good reason to stop playing games. Gaming increases your motivation, knowledge and skills. A good design can foster cooperation as strangers team up to tackle wicked problems or it can challenge players to compete against each other. But games can also be boring, over complicated and turn peoples minds off the task or the topic for good.

This panel discusses the positive effects, and the challenges on how to use serious games as a research tool.

Film screening and discussion

Jupiter, 5th floor
Thu. 05.10.2023, 20:30-22:00 

The film program presents selected archival and current films which focus on cities’ struggles with rising sea level and floods. The films present different ways to raise public awareness and less academic strategies to cope with spatial transformations and their impact on everyday life: They celebrate ambitious technical solutions against flooding, mourn about abandoned cities or call for the sea to be understood as a new habitat. This comparative view on communicative aspects of water-cities’ strategies invites us to discuss the connection between climate change, technical solutions, and the impact both may have in the future on space and society.

By/with Luca Iourio, film archivist and doctorate in urbanism at TU Delft, Janina Kriszio, visual anthropologist and researcher on potentials of documentary film in urban planning processes, Kristin Siebert, freelance film director and author for TV-documentaries and Jan-Ph. Possmann, cultural researcher.

CityClimate meets CreativeCoding is a collaboration between the City Science Lab at HafenCity University Hamburg and Kulturstiftung des Bundes, with scientific support by The Climate Service Center Germany (GERICS) and scientific evaluation by the Institute for Transformative Sustainability Research (RIFS). The Festival is a collaboration between the City Science Lab at HafenCity University Hamburg and the Centre for Urban Science & Policy at Delft University of Technology.
