Very first post here! I just started messing around with processing for android over the weekend and made a really simple drawing app that I'll be adding features to as a way to learn more about android app development with processing.

The app I made is a real simple drawing app that generates random color circles as you drag your finger across the screen and would like to add the feature to set that image as a background once you're done drawing.

Here's a screenshot of how the app looks on the phone (running on Galaxy Nexus).

Any guidance/feedback would be awesome. I made the app thinking of my daughter and she loved it, she actually made that drawing.

Thanks!
