This snippet is an idea I have been meaning to try for sometime. It's a mini-drawing program. You can draw single gestures (shapes, letters etc...) and the program then randomly scales, rotates, tints and translates these gestures repeatedly on the canvas. You can continue to draw as it does this, the more gestures you draw, the more the program will have to randomly choose from.
Have a look at the swf here...
