This software application is quite interesting. It allows you to pick images from Flickr based on their colour (thanks, Dominic!).

It’s not quite obvious what this is good for, though. Apart from stock photo agencies who would want to look for images based on colour? It’s one of these cool ideas that, when realized, turn out to be quite useless - useless in the sense that life without it is about as good (or maybe even better). Another obvious example for this category would be a cell phone with a little camera inside.
