So recently I've felt like building something with redstone on Minecraft. Yesterday I built a vending machine, and that was really fun, but it was simple and didn't require much thought. I need new ideas. Perferrably ones that havent been made already, but if they have then thats alright. I dont want directions or anything, just an idea of what to make. Please nothing super simple, and also nothing like a 16 bit computer, because im not that smart.

Thanks.

(also if i didnt explain myself clearly enough or something just let me know)
