For me it's just showing a static image, no matter what browser I use. This one: http://www.apple.com/ipodnano/images/overview_hero.jpg

The Mickey Mouse clock.

Mickey Clock.

Doesn't work on any of the three browsers on my laptop - presumably it works on Apple's browser. Kudos to Apple on going the extra mile there.

If you look at the code it only has webkit bindings. It fails gracefully however in trident/presto/gecko, so no real issues in my opinion.
