Wow. I think I'm insane. I spent all day working on this
I made it for Photoshop CS2, I'm not sure if all the functions I used (namely the gradient maps) are available in any earlier versions.
The tut is HUGE, I'll warn you right now. Click "Download to Desktop" to view it (it's a JPG).
I give full permission for *Manip-Equips
to display this work.
