Sepia Mutiny Goes Foolish
The folks at Sepia Mutiny have brilliantly replaced their entire site with something, well, wierd - a day early, more the merrier.
The weblog link itself takes one to first a Wordpress site, and then a blogger blog purporting to be the real Sepia Mutiny, a victim of cyber squatting.
The main page itself has tons of inside jokes that are pretty neat.
