Pixel Rationing

With 100 pixels per person, and a collaborative editing/voting system, Swarm Sketch allows many hands to make light work of sketching. The first project is "Shark Attack" and though the drawing is child-like at the moment, it will be interesting to see whether the project gains critical mass or if it will be forever needing attention.

The site also has a good collection of links to similar projects, my favourite of which is Kevan Davis's Smaller Picture.
