Exactly the sort of site I love and hate at the same time:

http://www.dontclick.it/

Extremely innovative, it forces the user to change how they interact with the interface. There are some simple activities for the user to perform (in addition to navigation), and occasionally the user is asked if they ‘miss the click’. It’s interesting to see how engrained the activity of clicking is in our web experience. Do we need it? Maybe not…

And of course, on the flipside — this is a very rich, non-linear experience. How would a screen reader handle this interface? What about users who cannot navigate using a mouse at all, or have difficulty keeping their hands from shaking? Perhaps there is a reason why we are accustomed to forcible action-reactions: if I click, it’s because I intend to elicit a response. Users are starting to get used to hover effects on the web, and sometimes they are useful in surfacing unexpected information, but we need to ensure we do not disregard the benefits to the existing model..
