I'm not sure S60 really needed yet another photo browser, but Nokia Beta Labs has gone and released one anyway, at least in 'experimental' form. Nokia Photo Browser offers a fluid wall of photos (see screens and video below), with 'magnifying glass' feature and 'face detection' (swipe from face to face in a group shot). It's very limited though, in that there are no menus or ways of actually doing things with your photos. My guess is that some of the 3D tech in this release will make its way into future S60 5th Edition devices. Anyway, enjoy for now.

Note that some thumbnails are still 'building'
