It's the flash with "Our Services" "Our Products" "Contact" in it.
hope someone can help!
This one seems good: http://jqueryfordesigners.com/coda-slider-effect/
Or maybe the AnythingSlider.
There's a list of these things, you can try these out if the above two aren't suitable.
Yeah, but you want people to pay £19 to use it. I'd rather put up with jQuery's presence and get a similar effect for free (and with smoother sliding too).
There are loads of free JS slideshows. And some people have compiled lists (see 4th result).
