another ascii art program. I made this a couple nights ago just for the fun of it. Very crude and the ascii isn't very good due to resolution problems, but it was fun to make
Ascii art!

lets see if I can get this to work... (well, can't find a way to do fixed width font, I thought the
tag did it, but evidentally not...)
(edit: duh, I didn't even think of the source tags, or at least I didn't realize it formatted it as fixed width, thanks rob!)
