Garrett Miller does it again. First he rocked us with Imaginawesome (where he turned kid doodles into complete illustrations) and now he's invented a whole new form of doodling; where dry erase markers meet windows.

They are funny, they interact with their (often) scenic backgrounds and best of all, they are quick, improvised and temporary. The perfect definition of doodling.

My favorites are below, but you really should visit Windoodles to see the growing collection (he's even taking submissions).
