Not so pi-specific, but I think I've watched Wayne post the phrase "standing wave" more times than anyone on the web so thought to post here.

Part 3 is a bit cooler when he levitates some balls in the standing wave. The temperature/density refraction thing is cool, too. Well, it's all more interesting than doing my Saturday work list... Part I starts here if you want the start -- that's the sort of room acoustics demo Smile

Almost makes a guy miss school. Hope everyone is well!
