pendulum waves

this video of a series of swinging pendulums of different lengths is a lot cooler than i thought it would be! the time it takes for a pendulum to go through one swing back and forth (its "period") gets longer as the string length grows. longer string = longer period.

It's got legs! Jerry Coyne just posted it, along with a
link to the Harvard website that gives that mathematical explanation. A commenter on Coyne's blog added a YouTube video of Steve Reich's "Piano Phase" which is sort of an audio equivalent.
