I think I get the gist of this – you can lock the spatial relationship of two objects such that if you move one, you move the other. And that only part of the spatial relationship can be locked so that objects can move along a predefined axis. Definitely amazing technology. A couple things I don’t get – like how expensive is the prototype and why does it need to be so cold? And maybe most importantly, why do the fingers in the video get to move the disc but then it stays were the fingers left it? But as with any new technology, I know it’s a long way from being put to practical use, so cool to see it in its early form.
