Artist Luis Carrasquillo sent us this amazing piece to share, which includes just about every major Nintendo hero (or hero appearing on a Nintendo console) there's ever been.
At 4000x, it's only wallpaper for the more hardcore among you, so for everyone else, it's like a Where's Waldo/Wally. Only, with Marios everywhere.
If you want to cheat and find them all, Luis has listed them all on his Deviant Art page.
