Application 1192

I have built: -an automatic TNT cannon with a 50-shot clip and changeable range -a non-automatic TNT cannon that compresses 176 primed TNT into a single block before they explode. (It shot me out of the top of the world.) -a self-repairing stone house -a compact piston elevator (By compact, I mean the elevator itself. The timing circuits are NOT compact) It uses 13 sticky pistons in a vertical line to extend sequentially. Retracting it has proved complicated, but it usually works. I haven't worked out all the glitches yet. -a particle-based player detector connected to a monostable circuit/rapid pulsar combination that shoots fireballs out of dispensers continuously whenever a player approaches. -an order-sensitive 12-lever combination lock -a system of note blocks and ABBA switches that plays "Twinkle Twinkle Little Star" -Many traps, including: -a block update TNT trap -a tree rigged to explode when any part of the trunk is destroyed -a sticky piston suffocation trap -a sticky piston pit trap -a piston-based arrow trap (When the piston retracts, the arrows fall) -various landmines, many of which are inescapable once activated -If I make traps, I will clearly mark them.
