I had this idea for a clock the other day and I decided to model it before posting here. This would basically be a clock that you can stick different cartridges into to make it output different countdowns and stuff.
For example, you can put in a meteor cartridge (just like how you would put a vinyl in a vinyl player), and it would have a countdown to when the nest meteor will hit as it's logic output (obviously the cartridge would cost a lot as to not make the Jr. Scientist useless).
You could also have it display stuff like in game time, when the next thunderstorm will be, etc.
