Recently acquired Minecraft along with the rest of our circle-jerk. We played for three days straight, then got bored, so me and Toaster used the give command to spawn an ass-load of TNT. Then we dug a 11x14x13 block hole. Filled 4 different 2 block tall layers with TNT, and blew the whole thing up. If my calculations are right we used about 1456 blocks of TNT, it took about 1 hour to set the whole thing up. Here are the pictures.
Before.
After.
