science tattoos

carl zimmer at the loom blog is collecting pictures of
scientists and their tattoos. he has a pretty huge collection now at his flickr gallery.

i've wanted another tattoo for a while now and recently i've considered a science tattoo. what better than science and art? i've been thinking about it and honing in on my science tattoo idea. i think i want a colorful spiral galaxy on my arm somewhere... i'm not exactly sure and i'll have to find an artist to create a cool looking spiral from some photos i have. what do you think?

more importantly.... do any of you have cool science tattoos?

here are a few of my favorites from the gallery...
