That's part of why I thought it was so awesome too!
I just found it searching random stuff on Google Image search. That's where I find most of my random pictures. I'm glad someone else thought it was as awesome as I did! :)
I wish I could remember how I found it so you could find more work by the same photographer, and maybe ask them questions about it. Let me see if I can replicate the search, that's hard to do sometimes though because Google updates their images all the time. I'll do my best!
