I took a lot of pictures at Austin this year; the F1 cars, the Ferrari Challenge, the Porsche SuperCup, and the crowd. I put some up on Flickr. None of the F1 race, as there were just too many heads in the way on Sunday and I didn't want to leave my seat. Most of the F1 drivers are identified but some are not. The car numbers are mostly very hard to find and helmet colors change. Not professional, but they give an idea of what was going on.
