Knight Cube Gang

You are a ton of material up and your opponent doesn't resign? You want to teach them a lesson about (dis)respect on the chess board? You have four pawns left, or a knight and three pawns etc? Just make four knights and checkmate your opponent with a knight cube.

Lounge for enjoyers of the knight cube, be it with or without rook for easier conversion. Post your knight cubes for bragging rights.
