You do this with a whole lot of JS basically. jquery seems to be the main culprit, but there are a couple of different scroll scripts in there as well. The scrolling bits are the important part, the background is gigantic of course, and the little rollover boxes at the bottom are anchor pointers that use the autoscrolling feature.
Vince Flanders, in his humorous and illuminating site ‘Webpages that
Suck’ calls this sort of thing ‘Mystery Meat Navigation’ and cites it
in his list of to ten crimes against good web design - mainly because
anything that gets in the way of easy navigation sends people
scurrying away from your site at enormous speed.
At first I held down my control key and all that happened was the
right click set of options you’d get with a mouse. When I twigged that
you just move the mouse rather than clicking, disorientation rapidly
kicked in. What’s so wrong with clicking? Lost interest in about 2.5
seconds.
And what’s the OR bit about? Really dumb stuff imho-- don’t bother
with it. And don’ try telling me that ‘well man, young people will
like it and its like a whole new way of navigating.’ Got my seventeen
year old web savvy daughter to have a go and she hated it.
