What is the one way you could improve Tetris? By making it alcoholic. Czech designer Martin Zampach’s concept product would let you make Tetrad-shaped ice cubes to drop in your G&T, or you could use the thing to make Tetradinal jell-o shots, perfect for your nerdy parties. I like the idea of them sliding down my gullet, forming lines in my tummy to be digested for drunkness points. I desperately hope that this thing becomes real and, unlike the Tetris bookshelf, does not cost an absurd amount of money.
