Where? What? When? Great Flickr Mashup

This is a small web app that uses new Flickr API methods to show where in the world photos have been taken. It will show photos with a particular tag, or, if you authenticate, photos from your friends, contacts, or yourself. The size of the circle on any given place indicates how many photos were taken there.

You can click on a circle to see photos taken in that area, or zoom in if there are lots of overlapping areas.
