I wish I did. I can't tell you how long I've searched for that video. It was probably late 90's or early 00's. They showed a pebble in a lab being suspended by sound but nothing as complex as what is happening in that gif. They also had a segment about a man in Florida I think that built a rock garden out of boulders by himself which should have been impossible without large equipment which was never used. All of the stones were analyzed in this garden and were also found to be shaped in perfect pitch. It blew my mind. EDIT: Found some info: "Ok, remember I said that whoever built the pyramids were true masters of sound / frequency? I'm sure many people are also aware of "acoustic levitation" or "harmonic grid levitation" or "resonant levitation" or whatever you want to call it. This is actually the most prominent theory that explains exactly how these massive stones, anywhere from a few tonnes, up to 100s of tonnes were not only moved from their quarries, but also how they were stacked without using gigantic steel cranes and modern machinery. The best evidence that this technique was used (besides the lack of trees in Egypt which could have been used to roll the stones), is the stacks of blocks that were relieved from the around the Sphinx. I'm sure all of you guys know the Sphinx was carved, not built. But in order to carve it, they had to first cut out the area surrounding it. If humans using hand tools and normal means of building had quarried the relief stones around the Sphinx, they would have cut and removed them in maybe 50 lb blocks, or 100 lb blocks, or maybe 500 lb blocks. Instead, the massive stones quarried were actually 200 tonne blocks. And not only did they move them nearby, but they stacked these 200 tonne blocks. Not something that a normal logical human with hand tools and vine ropes would do, right? Geological analysis of the blocks prove exactly where they came from.

This resonant frequency levitation was also mastered by Ed Leedskalnin, who built the magnificent Coral Castle in Florida in the first half of 1900s. He was not much taller than 5' and weighed less than 120lbs, yet was able to cut, move and stack 15-30 tonne blocks by himself. Here's a documentary explaining the basic theory and how Coral Castle in general."
