In the past I’ve enthused about “PicLens,” a Web browser plug-in that enables crazy-fast 3D slideshows for Flickr, Facebook, and more. PicLens was renamed Cooliris, and the team behind it keeps adding slick features. I was delighted to see that the plug-in now supports the Safari 4 beta, can browse local files, display image metadata, and more. Check out the features page for more info.
