if someone can draw a field it can be used to as a background in an app i just pushed to extras-devel this morning
its called (surprisingly) sheepdrawing
and lets you draw sketches over the top of a selectable image (hence me wanting a background scene)

there is a submit button which runs an at the moment bare script that someone can work on to push completed sketches/pictures directly into this thread (it needs wget magic that i havent time to sort out cos I am in work today..)
i also put back selectable pen color, did a bit of testing last night.

ie get some shell friend to muck around automatic submitting, and we can all play pushing sheep pictures (or anything else..)

i request tmo username/password/threadid as parameters and push those to the script along with filenames of sketch and finished image)
it really does just need the bit of glue to push to server
