@ademalsasa hi Ade, thanks for the link to share!
I actually don't make digital painting. I make paintings using actual, real life, physical paint. I use those paintings in interactive digital installations, using lots of tools (raspberry pi, Arduino, sensors & electronics, Processing, Python, web tech and lots of other things - too many to list!) - it's all on my profile but I guess I'll have a think about how to present it more clearly.
For people who care about, support, or build Free, Libre, and Open Source Software (FLOSS).
