Endless Demonator

SkeletonKey Games' The Endless Demon Deck is a lovely bit of physical design: each card is cut into three horizontal thirds, so you can shuffle tops, middles and bottoms independently and assemble a demon that nobody has ever met before. Twelve of each band means 12 × 12 × 12 = 1,728 possible demons, and every one of them arrives fully statted, because the rules text is printed to survive the shuffling.
That is a card trick that a browser can do too, so I made it do it. Hitting Summon Demon picks one third at random from each band and slots the artwork together.
