The Man, by Larry Harvey, Rod Garrett.

In 2009, the Burning Man rises above a 'tangled bank' consisting of irregular wooden triangles. No two elements of this organic composition will be quite the same; together they'll create what's best described as a chaotic truss.

The truss is clearly inspired by the "belgian waffle" installation from 2006.
