Make some art with your phone sensors

Even just the plain etch-a-sketch using motion sensing is cool enough.

I suppose this might have been done already?

I did NOT know the motion sensors on my phone were THIS precise, that’s surprising

change paint brush size -> whistle

change color -> put finger in front if camera

make drum sound -> tap side of phone

Is there a reliable way to trigger percussion?

A digital theremin! Very fun.
