I wanted to try something involving putting the picture in, having the program spit a pixelated picture out, then using that as a guide for a creation on powdertoy. any ideas?

EDIT: map=>guide

no, no, I meant that I would use that as an art reference, not something that would be active within a program. for example, I take a screenshot of a gun in a flash game and color one like that in powdertoy.

?wat?

where has this been my whole life???

btw if you're a mac user, use a program called afloat http://www.macupdate.com/app/mac/22237/afloat
