Okay, I’ve watched the video three times now, and I still don’t entirely get what this thing is actually used for.
But I’ve run it through the Techi.com buzzword checker, and the readings are off the charts. “3D”, “iPhone” and “hovering” are all included, plus the device was custom-built.
Essentially the device, called a Floating Forecaster, uses airbed pumps to raise a ping pong ball a couple of inches in the air.
The cool bit is that the 30 airbed pumps are controlled by a touch app on an iPhone, with the user able to exert an amazing level of control on each ball, or multiple balls.
Go check out the video, and feel free to provide translations of the video description in the comments.
