It's a neat concept that takes traditional picture editing a step further by allowing you to doodle on your phone, then have it converted to an official Android object. You can draw any sort of picture, including cartoon drawings. The idea is to allow you to draw something with a pen on your phone, then have it converted into an Android-ified one (such as a phone, icon, or screen). If you've seen the new Android icons, chances are you have one of the many apps PixelLab - Text on Pictures.
