PicLens is a free plugin that transforms your browser into a full-screen 3D experience for sites such as Flickr, Facebook, Picasa, Google Images, MySpace and more.
Piclens was always an esssential plugin, but this release includes new features such as video playback and search functionality. YouTube is your friend.
IE and Firefox for Mac+PC have already been updated and using Piclens with Firefox 3 on Leopard is a super smooth experience. Safari should follow soon.

UPDATE: PicLens is now called Cooliris and Version 1.8 is now fully compatible with Safari 3.1
