Minecraft: Choice Lock (With Schematic)
Channel: ZaxPlays
Date: 2012-01-10

This nifty little construct gives the player a choice of three options.  Each option activates something (to be determined by the person implementing this construct), and renders the other options useless.

Requires manual reset.
