I know this is a long way to go for a "The Beam Rifle looks like a dustbuster" gag, but since I've never put the Flood in a strip before I thought I'd kill two birds with one stone.
UPDATE:
Louis, in his infinite awesomeness, has added a way to get an RSS feed thingy for notice when new strips pop up. A reader asked, The Great Wu answered. Woot.
Here's the link he sent me about it.
