Amazing water and sound video!

Hey guys, came across this video this morning and thought it was cool enough to share.

That is neat. I live on a lake. My front yard ends at a seawall that is roughly shaped like a very shallow U. Early in the morning, before there is a lot of boat traffic and the lake is calm, when just one boat goes by, it is very interesting to see how the wake bounces off the seawall and goes back out onto the lake. I'm sure someone more versed in room acoustics would be able to apply what they see here to help them understand how sound reflects. If a boat goes by at just the perfect angle, the U shape acts like a magnifying glass and concentrates the waves at a common point and instead of waves you see several inverted cone shapes rising and falling.
Wish I had video, but no camera capable of decent shots.

The apparent forward and reverse movements are caused by strobing with the 24 fps rate of the camera. It's not visible in meatspace.

I see. Thanks for pointing that out. Still pretty cool.
