Buy Jan a coffee

Programmer and 3D artist from Czech Republic, open-source enthusiast. Author of Sketchbook, among other things.

You can "buy me a coffee" if you found my code useful and want to encourage me to keep improving Sketchbook. I've already spent 100+ hours of work on the project and gained nothing in return, so if I get a hint that it's worth at least as much as a cup of coffee, it'll go a long way in motivating me to continue working on it.
