To answer the original question:
Doug Triggs, the logo designer, put that in on his own whim. I'm tempted to come up with some sort of contest to see who can come up with the most creative guess -- but of course we'll get a few dozen responses from people who can actually read it, which would suck some of the fun out of that.
Anyway, he tells me, and I must take his word on this, that it says "DANGER DEATH RAY."
