TO START BACKGROUND ANIMATION: Open a Game, Select player(2+ accounts required), when game loads press home. Note: Close the game to stop it restarting the animation when selected. Tetris blocks scroll vertically in a stairstep pattern. Blocks rotate and shift position in alternating directions. Text color is blue/green (usd 97 and 17). Dialogs scale in/out and hide hint text. This is the sharpest looking theme and my personal fav so far.
