Don't put that on your desktop, it's puny and crappy. Send me a PM or an email and I'll email you a 800x600 version of the original image (minus the logos and titling and crap).
I like that Joshy, what did you use to make that? I like how it's all "vague" looking, like it takes you a few seconds for your mind to piece together what it is.
I used paint shop pro, first i drew the drawing, just the obtuse part. i drew it in red like crayon marker. then I gray scaled it, and put it on a black background. then I made the lil pieces to look like bones and branches, and then mirrored it.
