Data interactions in parallel coordinates

Processing is growing on me. Inspired by the different and (very) interesting data visualisation examples I’ve seen, I decided to take a shot at interacting with the parallel coordinates that I generated here. Of course, I had to reduce the number of samples for this demonstration; it’d slow to a unholy crawl otherwise. For this video, I’ve taken 300 samples. The interaction is essentially a mouse-hover highlighting of any sample(s) under it. I fiddled with the colors a bit, but decided that a white-on-greyscale scheme would show up better.
Of course, I still haven’t gotten around to labeling the axes. This I’ll probably pick up next. But as the video demonstrates, there’s a lot to Processing than meets the eye.

PS: By the way, the actual demonstration ends around the halfway mark; I was trying to figure out how to stop the bloody recorder.
