Standard desk lamps with shades are a thing of the past (and super boring), but the Tetris Desk Lamp made by the official Tetris Brand is another story. The stackable tetiminio blocks will apparently light up when stacked on top of one that is already lit, although we cannot find an explanation online as to how this product actually works (or how one block is lit up to begin with. Batteries? LED? Your guess is as good as ours). The best part about the Tetris Desk Lamp is that you can configure the lamp however you want – tall, short, squat, long…it’s up to you and how you want to arrange the colours and play the game.
