found a pretty sweet flash tool that might be useful for some people. i dont recommend drawing them on 2draw and crapping up the boards with 30 second doodles.. but maybe oldschool sketchbook and pencil. or even using them for references for bigger pieces.

Gigandas posted something like this waaaay back too.. good practice for figure artists.. I cant even tell what I'm supposed to start with in 30 seconds on people.. lol
