You may recall from a Mechanics course that the period of a pendulum is proportional to the square root
of the length of the line suspending the weight - i..e., the longer the pendulum, the slower it swings.
Some Harvard students built a device with a series of 15 pendulums in a row, each one slightly longer than its neighbor, then set them in motion and filmed the result.
It is simple direct and inverse relationship driven but it is also quite mesmerizing to watch..
