I woke up this morning at 5 a.m. with an idea for an art project: the temple. It's a tree that gets filled with people's messages written on the slats from palettes which form the "leaves". Yurt-like structures surround it if I remember right, although I think a larger structure to enclose the trunk is the way to go.
I realized I had no choice but to proceed. I e-mailed some of the art people at Burning Man and they said that the Temple is considered one of the art projects in the normal grant process. Grants are due at the beginning of February, and the cycle hasn't started yet. I started looking into it.
