In 1980s, SIMON was all the rage. SIMON was a memory game in which segments of a circle lit up a particular colour in a particular sequence. The player then had to reproduce the exact same sequence to progress with the game. Les Pounder has taken a Raspberry Pi and a bunch of components from CPC (bet you couldn’t guess that) and put them together in a large box to make a very blinky version of the same game. You can read how to build it yourself, and program it using gpiozero (and some other libraries) here. If you want to do it on a smaller scale, you could do it with some illuminated momentary push buttons!
You can see a demo video of it working below:
