Grant French is building the Minecraft equivalent of a sand mandala. He figures it'll take about 72,000 blocks of wool. It's 310 x 310 blocks from edge to edge, and it's going to take a LOT of sheep-punching. When he finishes, he plans to burn it down.
“I started the project with the intention of self discovery and understanding some of the principles and mindsets of the Mandala process. But I have to admit, I did want some fame out of it.”
