Trippy! Is that a Haeckel-style radiolarian right below the brain? I think it is.
That's my guess too Emily! I love Haeckel's radiolaria - they look so much like something Buckminster Fuller would have come up with.
Found the source-- it's at the center: http://en.wikipedia.org/wiki/File:Haeckel_Stephoidea_edit.jpg
Haeckel's images of radiolaria really are amazingly beautiful, even if real ones are a bit less crystalline and symmetric.
Trippy indeed! It reminds of Rick Griffin's posters, circa 1969.
You have inspired this Australian that she needs to one day book a trip in order to be part of the Burning Man Festival.
Is it possible to buy a Burning Man Evolution 2009 poster? I went last year and really wanted to find one to remember my first trip to Burning Man.
