Comment Here's one from an actual LEGO tech... (Score 1) 86
I worked for nearly a year doing tech support for LEGO Mindstorms, and I can tell you about some really weird ones. However, my favorite was the one my manager built. It would, when the top panel was pressed, use a light sensor to follow a black line of tape to the refrigerator. It would open the door (it was a small refrigerator), reach in, and if a beer was in the right place, snag one, then follow the black tape back to him. While he still needed to get up every other beer to put one in the right place, it's still a fun idea.
