A falling-sand world where each pixel is an element with its own rules: sand falls, water flows and puts out fire, plants creep along anything wet, and wind pushes the lot sideways. Finished scenes can be posted to a shared gallery for other people to poke at.
The plant element is the trick, because drawing one wet line grows vegetation on its own and turns a drawing tool into something that keeps working after you stop.
