If I was any good at MS paint, I'd try to redo some of my old work that I did with a pencil and paper set.
"Use what-the-heck ever artsy program you want! The core of the MS Paint Challenge lies in limiting yourself to the archaic software built into the operating systems. That being said I don't want to restrict anyone who would want to participate. Also, don't submit old works! Each entry must be a fresh idea for the week's challenge."
go into photoshop or some other drawing program and start drawing >:/
it doesnt have to be good, just has to be on topic!
