Piston Trap - Transforming room

With Minecraft's 1.7 update, lots of players have been making amazing inventions with the newly implemented pistons.

I (ChongJ) got inspired to make use of the pistons as well, and ended up devising this piston trap. The trap "transforms" the room around the victim, catching him off-guard, and trapping him until the lava finishes him off. This video both showcases the trap, and explains how to make it.
