I recently discovered this amazing online flash-based drawing application called Odosketch. It recreates the physical experience of sketching on a pad of paper with a variety of pencil colors, sizes, textures and imperfections that are supposed to make you forget you're sketching on a screen. The best part is this: when you click on one of the featured drawings, the playback allows you to view the artist's brush strokes from the beginning to end, including mistakes...like the tree above. How cool is this!!??
