i do all my pixel art on an ipod, so no special effects for me.
pixation or pixation+ or something
The only good pixel art app for free imo is Pixen, but that's mac-only and I don't have a copy of Parallels to run OS X on Windows.
paint.net??
That's only for Windows bud. He uses OSX.
probably because you were the one that recommended it to me.
Something I made a while ago.
