For the lab day at EMBL in 2023, I developed a small computer game to illustrate how motion is different for organisms living at different scales. It is inspired by Purcell's paper Life at low Reynolds number . For a bacterium, friction forces dominate over inertia, whereas for larger organisms such as swimming humans or whales, inertia is dominant. The ratio of inertial over frictional forces is called the Reynolds number. In the game, you control a whale or a bacterium with a controller and try to catch the Erzberger lab members who are trying to swim away from you. You have to avoid being caught be professor Reynolds. The game was coded in the Python library pygame .

In 2019 I participated in the project 'Science figured out', or 'Wetenschap uitgedokterd' in Dutch. After a workshop from the The Floor is Yours , we had the opportunity to record a 3-minute movie about our research. Here is mine. The beautiful decor is a room in the Arenberg castle in Leuven.

In May 2019, Felix Nolet and myself prepared a presentation for the Pint of Science festival. We explained how mathematics pops up in the real world around us. The presentation was in a pub which made for a very nice atmostphere.

Together with my colleagues from the Gelens lab, I organized workshops for children in the framework of KU Leuven's Children's University. The goal of the workshop was to show how complex patterns, such as those we can see as stripes on zebras or spots on leopards, can arise from simple rules. For this, we used Wolfram's elementary cellular automata with large cardboard plates, to emulate a growing pattern.

In December 2020 I made a small video for the Solvay Workshop on Physics of living systems. I explained a central idea of my research in about one minute. The video is a bit unpolished but I did have fun making it. For the interested: the animations of the dividing egg and pendulum were done in Python. For the writing on the blackboard I used a Wacom drawing tablet and the drawing software Krita. The ethereal synth music was recorded with my old electronic keyboard.
