I've just remembered something I saw, about 6 months or a year ago. And dam me, I can't remember what it was or where I saw it. It may have been someone Apple demonstrated, or could of been part of a game, or even an experimental user interface from some company. It just struck me, THIS is where I'd seen the general concept of Apple's zooming circles user interface. It may even have been in a computer news article. A desktop or UI where you could have unlimited icons, you scrolled the whole screen about, and could zoom into clusters of round icons. From memory, and it is vague I will admit, it could even of been the basis of the idea for what Apple did. What I'm thinking of may of been an Apple demo, but it was long before the watch was shown. Can anyone remember what I am talking about? there was a video showing it.
