Starting off with the oldest thing I can find, here’s a video of a digital logic design project last semester. Using a shift register, 7-segment display (and driver), some LEDs a push-button and some NAND gates (I think it was NAND, I don’t remember exactly; might have been NOR gates), we had to simulate a dice roll. It’s pretty much just cycling through 1-6 in a non-linear order really quickly, so what you get depends on how long you hold the button down. It changes really fast so you can’t really time your presses to get the desired number (I mean, unless you have super fast reflexes).
