That's nothing, I think it's even cooler to see what people can do with just command blocks (which are basically redstone activated console command scripts). Even cooler still is the people who forgo even that and do cool things in redstone exclusively. Redstone computers in minecraft have been a thing almost as long as redstone has

Oh hey, I did a lot of ComputerCraft back in the day. Don't forget OpenComputers, which was much different flavor of challenge but also quite interesting.
