Hans Lemurson builds redstone computers in Minecraft, which led to the joking question of whether he could build one that plays Minecraft. Well, the answer is yes, sort of.
This is a very crude 2D platformer that allows you to move around and modify terrain. "It's not truly Minecraft, but it's about as close as you can come with redstone," Lemurson says.
Yeah, but can you make that make Minecraft and then play both? Hmmmmmm?!
