Well, the animation itself looks nice and is really something different, but I doubt, there are many animations that can help to introduce real advantages over non-animated, rectangular, grey boxes.
First off, there are two main reasons that might recommend the use of "old-fashioned" layouts:
First is the compatibility for disabled people the require special accessibility software for interaction. Special UI types would require those new interfaces to be compatible with existing accessibility software, which is far more complex than one could think.
A second reason for mostly rectangular interfaces is that most people are used to them. Every new interface kind would somewhat require "special learning" for some (if not all) users. If you're first-time user of a special device class like a mobile phone or a router you might have seen something like it before (or maybe not) and your first information to look up will be "How to interact with it?". And something simular goes for new kinds of (G)UI structures.
Well, it would really be funny, if you just lay in the bed, asking your microwave to cooksome meal while telling your robot to grab it for you when it's done. Or as it's shown on some Microsoft ad for
Microsoft Surface where you could just tip on a table to play movies. It's all just a matter of time when we will be used to such devices and aare required to think behind old-fashioned the patterns of known software design. But for this to become reality it will also require developers and customers to change - The question is which ones first.
But regarding other UI ideas: What about doing UI in third dimension, like 3D desktops (known from Linux world and SphereXP)? What about better integrating such possibilities into the development tools to work with?
It's simply not easy to rewrite full UI functionality each time an app is to be written. As such, manufacturers for such tools are asked, but also developers to request for such options.
But at the contrary: If visual interfaces are(?) that much better, why are many people (doctors, opticians, ...) still using mostly text-only based UIs?
In fact: I'd reject working with an UI consisting of circles moving around all the time

It'ss funny-looking, but not suited for real work.
