That's weird --- I looked at some of the sample animations, and I could swear I heard a tiny voice shouting 'Oberon! Plan-9! Rio!' in my ear... I'd like to try something like this in action; but the problem, as always, is going to be bootstrapping. Look how badly Ubuntu manages something as simple as putting the application's menu bar in a non-standard place. ...I worked once with a desktop environment for the PC, GEOS. It had a feature where your application's UI was described in logical terms and this was then mapped to a physical UI when the app loaded. It allowed pluggable look-and-feels to drastically modify the look and behaviour of the application as they saw fit. If we had something like that, this would be easy. Shame we don't, really.
