I loved Tetris as a kid. I played the gameboy version for hours. I now have it on my phone and iPad and find myself playing it when I'm on a flight, or bored, waiting for something to happen (which is never these days). Whether I'm playing the game a lot or not, the idea of making tiny boxes fit in neatly and clearing out rows of work in ingrained in my brain. It's what I do on a daily basis when sorting out who will work on what; it's what we often call "resourcing." And it's one of my biggest project management challenges, for sure.
