The Week Links: 13

During my time away in Australia, The Week Links posts will continue...with a twist. Rather than links to posts I discovered in the prior week, each post will have a specific theme. This way, I am able to create and schedule them before I leave. 
Today's theme: Interactive Art Websites (better known as procrastination tools)
Picassohead
Scribbler
DIY Jackson Pollock
Art Pad
Cornell Boxes
Kaleidoscope Painter
Bomomo
Graffiti Playdo
Myoats
