The internet is an interesting place full of crazy ideas, and Samperson, a "game design criminal", is one of the contributors. Yes, it's that guy who created Desktop Goose, a fun but extremely annoying anti-productivity software that introduces a goose who will keep pestering you by leaving mud footprints, stealing your cursor, and dragging out your pictures and apps for anyone to see.
This time, Samperson came up with something less evil but still cool. Did you know you could use Notepad as MS Paint? Well, you can with his new invention. It's simple: you just draw whatever you like with hash signs (and possibly other symbols). You can change the color of the brush, decrease or increase its size, hide UI, and "evaporate", or clear the canvas.
