No, you're not on PCP -- this blog's color scheme has changed for the next few days so as to participate in the "Maroon and Orange Effect." The entire country has been invited to join this and pay tribute in a symbolic way to the kids at Virginia Tech, both those who were killed on Monday and those who survived and are soldiering on.
Brian at MGoBlog passed along info on how you can slather your own blog with Virginia Tech colors: the hexadecimal codes are #660000 (maroon) and #FF6600 (orange). I hesitate to give you any more instruction than that, because what I know about HTML can just about be squeezed into a thimble, but I'm sure there are qualified Internet professionals who can tell you how to fine-tune this if you're so inclined.
I'm sure that even my parents, both proud University of Virginia graduates, are shouting "Hokie, Hokie, Hokie hi" today.
Rock over London, rock on Blacksburg.
