I was staring at it too long and now I am useless to any tasks that involve brain power ;-]
The B&W version is my favorite, but i have always favored tonal work. I see tree roots and aliens.. somehow I think I am wrong in this.. I LOVE it though :-D
Well you aren't too far off. Original base image (many mutations ago) was root system of a marijuana plant I grew, photo taken some months after I pulled it from the ground and tossed it in a brush pile so the root ball was starting to decay and melt. Then I went all alien process on it and mutated the crap out of it. Which does induce aliens.
