The "Mojave Experiment" and funky interfaces.

An interesting bit of research / propaganda / anti-propaganda (beats the hell out of the now stale Mac vs PC ads), it's sneaky but fun :-)
The "Mojave Experiment"

Apart from the content itself, I really like the presentation style - something about these random responsive "water-bed/bouncy castle) interfaces that let you decide what you want to look at - without any real logical path or conscious reasoning behind what you click on is so much nicer than the usual "here's a bullet list of all our testimonials". It would be pretty interesting to track the clicks on this kind of interface and analyse usage patterns to see how people interact with it.

Another nice interface I came across recently was the Hard Rock memorabilia site, which lets you zoom into hundreds of different bits of memorabilia from signed photos to guitars. The detail level (at full zoom) is pretty underwhelming since I was led there by an article that was talking about the incredible detail availble in Silverlight.. but fun to play with anyway... http://memorabilia.hardrock.com/ (you'll need the Silverlight player from http://www.microsoft.com/silverlight/resources/install.aspx)
