Channel9 has a rather long video from the XNA Game Studio Express launch event last month. Not only do you get to meet the famous George Clingerman, but in the middle there is some footage of yours truly demonstrating a splitscreen shooter game I wrote to test out the framework. Now if only a) I'd bothered to work out what I was going to say more than ten seconds in advance, and b) they hadn't cut out the bit where I explained how my funky reflective ground shader works :-)
