SNAPaint is a basic 2D raster graphics editor built with the Snap! programming language.
It's nothing more than a roughly one-month project for a freshman computer science class. DO NOT, I REPEAT, DO NOT RELY ON IT. I have no idea in how many ways this thing could break. The canvas size is limited to a 2005-era resolution anyway. And the execution speed is positively horrific. Just don't. Just don't.
