Lack of imagination doesn't mean this isn't innovation.
It's the ability to convey more information in less space.
Top-of-my-head notion: The cursor spins (or changes in another way) to reflect CPU use, or bandwidth use, instead of taking up space elsewhere on the screen.
The same was said about Compiz, but it turned out to be a passing gimmick that looked flashy but didn’t really add anything. Sure you could always make up reasons why it’s useful, I remember the same about Compiz, but… is it really? I could be proven wrong, of course, but it hasn’t been demonstrated yet.
It’s a solution in search of a problem. OP should have presented it with a real use case or benefit, not just flashy graphics, if it’s meant to be anything other than a fun oddity (which, to be fair, is perfectly fine).
