Real Time Art.

This whole Web 2.0 thing is pretty darn fascinating and not least in the whole pile of mashup technologies is Flickr with its extensible, how-about-this mentality.

As more and more people populate Flickr with their images it is only a matter of time until others use that art as their building blocks. A wonderful example can be found here at Clockr:
Clockr uses random digit images from Flickr to display the current time but if you don't happen to like one of the images, just go ahead and click on it...it'll change. So allow me to diagram that for you:

Person "A" creates image and uploads it to Flickr >>> Person "B" creates Clockr to diplay the time based on a community of "person A's" images >>> Person "C" (that's you) clicks on the images to change the art.

Tagnautica is an experimental navigation tool built to explore the space of related Flickr tags.

Even if your are not the type to appreciate forward thinking interfaces, you owe it to yourself to play around with Tagnautica a bit. Makes you go hmmmmmm.
