So lately, I've been playing Minecraft more often and consequently I've started to fool around with redstone again. It can be super frustrating but looking back at the monument of your achievements in game time and time again is pretty satisfying. I was just wondering if anyone had ideas for seemingly impossible mechanical structures that I could try to make a reality. So far I've made a 3 digit binary calculator, a revolving lighthouse, and (with the help of a tutorial) and 3x3 piston door. Just throw something reasonable at me or just tell me about cool things you've built!
