A cover for a new album by Phlogiston, named Geif.
See the process animation of the sprite being drawn here:
Phlog asked for a mozaic of tiny sprites and tiles that forms a skull, I decided to make it super glitchy-like. It was lots of fun to make. Made it with an NES color palette, but didnt really pay attention to actual NES limitations.
