experiential art ---- inspired by phil Hansen and others

This guy is amazing in what he does and how he does it. Check out his site.

I would very much like to do more with experiential art of this kind, making something in process, in community of some kind, and compiling the process in various ways.... for instance, he created the face of buch using names of fallen soldiers in Iraq, "as of APril 30th, 2005" --and a compiled photos of vitims making a huge rendering of Gary Ridgeway --- he used dandelions, must have been thousands, to create a large imge of Mother Theresa....
I have ideas, and the mind set.... to create in this way... It will happen.
I'd appreciate any other names, site you may know of in the same vein ... Thanks to you...
