Made after seeing the Vsauce vid:

The rules are very simple
you must move your L onto at least one new board space each turn. The L can be flipped, but can not overlap another piece.
if you wish, you may move one of the circular neutral pieces to any unoccupied board space (the color doesn't matter, either player can move either ring).
Game ends when your opponent can not move their L.
I have not printed it yet, but I have prepared the layout.
