Looking around for a decent Javascript gallery to use on ‘this site’ – I came across by far the most comprehensive and pleasant to use in: SmoothGallery2.0
It uses the MooTools library and has a slick interface. The only downside I’d say is that for large sets of images using a Gallery Set it can get slow and bogged down.
Having a sniff around the code of the gallery it looks like MooTools is well worth a look. Putting Prototype to shame and coming close to jQuery for slickness.
It also begs the question – why are people still bothering to use Prototype?
