While I agree, with the general consensus here, that the design itself is pretty useless in practice, I think that some of what they've done is kind of intriguing, from a mouse intent perspective. When I saw the label of a "clickless" interface, I immediately thought I would constantly be dodging popped in elements trying to get at other elements, but this actually happened far less often than I anticipated, mostly because it was designed fairly well for that use case. I think in general, mouse intent elements, such as pop up menus on hover, are hugely frustrating on 99% of sites. Just now I was trying to close an ad on the bottom of a youtube video, but the resolution pop up kept jumping in the way. Navigation menus are frequently the same way, they pop over other content without you intending it to do so, and then its frustrating getting them out of the way. Personally, I dont see the benefit of trying to guess what the user is trying to do by where theyre hovering, but a lot of sites do this anyway, and with some disregard to the side effects. At the very least, this site offers some interesting paradigms for a clickless UI, and illustrates a somewhat thoughtful design around that interaction.
