@Jeltron I didn't know about that, I like the concept. A simplistic smoothing algorithm is do-able, maybe harder for advanced ones (kalman, etc). Making a note. Re etch-a-sketch: - I should try adding MBC7 accelerometer support. Might be fun.- I got a gb-303 music cart from IG and was thinking about adding support for drawing with it's knobs (here's video of a little test app I made to read the knobs).
