This pyramid at the Louvre, commissioned by Francois "the Sphinx" Mitterand is allegedly by Dan Brown, author of The DaVinci Code, to have 666 panes of glass. I personally counted all of them using this photo, counting 2 half-panes as being one, and came up with 675. There are also 3 smaller pyramids surrounding the bid pyramid, each having 32 panes (again, counting 2 half-panes as being one). It certainly wouldn't surprise me if somehow the number of panes mathematically equate to 666; however, from everything I've read on the subject, there is no conclusive proof of this.
