I bumped into SphereXP yesterday, which is one of the experiments in desktop management that’s been going on for a while (well, ever since Xerox PARC I suppose). Here it is running on my machine.

If you have an interest in this sort of thing, I can reccommend you have a look. Whether it’s the future of OS interfaces I doubt, but it does give you the illusion of a larger monitor, and in the process shows you that perhaps trackerballs are the way ahead after all. It’s just very hard to get past the novelty factor, which is always a problem with these things.

I’m also having a look at this as well
