just found a cool way to view pics at Flickr:
Flickr Postcard Browser.
This application lets you browse Flickr's huge image database, by searching for tags (keywords). Flickr Postcard Browser use the real world metaphor of a set of postcards shuffled onto a surface.
Many thanks to the Flickr team for putting together a really easy to use API. Flickr is almost certainly the best online photo management and sharing application in the world.
