In case you're watching the Allstate 400 race at the Brickyard today on ESPN, don't be scared if for some reason it seems like your TV's gone the way of an old hypercolor t-shirt. Rather, it's a new teevee technology the folks at ESPN are calling "Draft Track" — and it's a way to see how the air is flowing over the top of the cars in situations where the drivers are drafting off the car in front of them. So don't worry, those mushrooms on your pizza are in no way magic. Well, probably they aren't.
