I've followed the herd and have converted the site to Movable Type. There are still some default templates that I have not customized so don't email me to tell me about them—I'm just too lazy to do them all right now.
I've added keyboard navigation to Figure/Ground. Now you can go through the photos with the left and right arrow keys. Tested to work in IE, Mozilla and Safari. Beyond that, I don't know and, frankly, I don't care.
