From Elonka:

I spent days scouring the web trying to find some sort of comprehensive list of James Sanborn's artwork, but no dice (Sanborn, btw, is the sculptor that made "Kryptos"). I even contacted his agents and asked for a list, but they said that there wasn't such a thing, and that if they were to ask the artist for a complete list of his sculptures, he'd probably laugh at them since there were so many.

So, I went ahead and made my own list. I guess this makes me the self-appointed head of the Jim Sanborn fanclub. ;)
