I'm in Cologne and like working on interactive installations, playful interfaces, and other things people can actually touch.
If you have a project, a collaboration, or an idea you want to talk through, email is the best way.
A short note about what you're planning, where, and roughly when is enough. I read everything and usually reply within a few days.
If we already know each other, Telegram works too. t.me/cstenkamp
Code lives on GitHub. Issues and PRs are welcome. 3D models are on Thingiverse.
