This is from the recent episode of Nature on PBS:
With a high-speed camera and vibrometer in his toolkit, researcher Damian Elias, featured in Part Two of "What Females Want and Males Will Do," is able to pick up on a courtship ritual few have ever seen before. He's discovered that male jumping spiders actually perform an elaborate dance — with coordinated vibrations, no less — to woo potential partners. Part of the 26th season of the Peabody and Emmy award-winning series produced by Thirteen/WNET New York for PBS, "What Females Want and Males Will Do" premiered over two Sundays, April 6 and 13, at 8 p.m. (check local listings).

And while there, browse the archives for more cool animal behavior footage from this series on sexual selection. Given that we are discussing sexual selection in class this week, I may post more of these videos here as well.
