This is quite neat. Just been playing about with some Adobe AIR products (AIR being Adobe’s “web” common runtime kind of thing), and came across Destroy Flickr.
It’s interesting firstly as a demonstration of what AIR can do, but also as a neat way of viewing Flickr. Again, like a number of other apps and sites, it benefits from a darker background for viewing photos (which personally I think makes photos look better and removes the need for users to put frames on their own photos which I’m not a fan of at all *). I particularly like the layout as if you’ve scattered photos on a table to browse through, and you can drag photos around, click on them to view larger and zoom in easily.
