|Tetris Ice Cube Maker|
This just sounds endless hours of mindless fun to me. I would be that person that would buy, like, 15 of them, add food dye to water and make colored frozen blocks and then spend an entire evening playing my own home-made frozen Tetris game. Hey, don't judge! I write for a geek blog, what do you want?
But, if you're normal, you'd just serve drinks to your guest with Tetris block shaped ice cubes in them and smile as they sip from the glasses, blissfully unaware that in the liquid swirling around are the shapes from a video game come to frozen life.
Okay, maybe I am weirder than I thought.
