Ive been doing a little messing around with Dashware and edited a gauge to use in my videos. Here is a video of my fastest lap yet at Gateway. Its got the gauge and a little track map. I think its pretty cool and should be nice for analyzing data with video. I think I will eventually try to make my own gauge that looks like my GPX dash. That'll take a little time to put together, though.
