After recently being "challenged," I thought I'd see what the rest of the community could think of to this build request. I've already done it, so I'm not idea hunting. No prize except for bragging rights.
The Challenge: Build a 32x32 square, 2 story building with no windows out of quartz and prismarine. In addition, only glowstone lighting is allowed. Redstone allowed.
I'll post my result whenever I can figure out how to get the picture up. . .
