This is an interactive screen saver: You may watch intelligent engine playing new tetris-like game, or play yourself. The game played is like Tetris but with different blocks: it keeps the glass from filling using a build-in intelligent engine. Its remarkable distinction from other screensavers is that you can take control over the game, and try to outdo the computer. Various adjustable options and color modes are included.
