Just doodling in a drawing box.
What is the drawing box?
Well the one in question is a little art box on TRPS (theroleplays.proboards.com) where any registered member can go in and draw. Whatever you draw will remain in the box until either you or someone else adds to it or draws over it. It isn't exactly amazing art software, but it's still fun to play with. TRPS isn't the only place to find this type of thing, it's just the one I use the most. It's fun when people actually log on and add to the image until it becomes a huge collab.
Lately though I'm the only one that draws in it. My last 5 drawings have all been Agito/akito drawings though XD
