Geert-Jan was invited for the Monheim Trienale in 2023 to make a instalation with Staalplaat Sound System, when he found the self driving busses in Monheim a thought it would be nice if i also filled one of te busses with my solar instruments. Originaly the plan was to put a solar powered drum set on the bus but in the end it was not allowed on the bus, you can see a picture of it at the bottom of this page. So it ended up on the info desk, where it was also nice. I didnt make agood picture of it, maybe on another occation.
