Gamehendge is a fictional land created by Trey Anastasio of the band Phish. I'm a big fan of theirs, and quite a few of their songs are set there, including some of my favorites. "Gamehendge Time Factory" was a song performed by them at their New Years Eve concert at Madison Square Garden in 1995. I've always thought the name had a nice ring to it, and I like the tie-in with the band's lore.
