Javascript thingummy

I’m still very much a Javascript newbie, but have been playing with it for one or two projects. I wanted to add a bit of colour/interaction to the Datawise Computing home page and came up with the site preview Javascript thingummy.

Basically the image at the head of the list of sites is a tall image with each site stacked one on top of the other. When the mouse moves over a site name in the list the image is scrolled to show the appropriate slide from the stack.

I know it’s quite simple, but a pleasing advance for a beginner.
