I had a lot more fun with that than I expected great work! I found my finger maneuvers not crisp enough to do anything with real detail.

One idea I immediately had was to use a key on the keyboard (if not on mobile of course) as triggers for draw, hover, erase, etc. You could also control different colors that way, possibly even draw generated shapes like circles and rectangles (press 'c' to start a circle, then use your finger to drag out the size, stop with 'c' again).

and if you want to get really advanced, allow rotation of the drawn object and then choose a new plane to draw on.

This would also be useful for making signatures when needed on a website.
