That was a really confusing website to me. Lots of pictures and none that really explained what it did. The main important piece is the video in the middle, but that don't look like a video unless you pass your mouse over it. And with a slow network connection, it didn't happen to be animated as I scrolled by so I didn't notice it until the second pass.

It appears to require a hard floor and I wonder if it would make grooves in the floor after a while.

Thanks for the warning! For others in the same situation, the direct link to the diagrammatic rendering video which best shows how it works is:

It's just a piece of forniture that moves side-to-side with electric motors when you push the switches.
