Dolphins is a pretty little web 'screensaver' type thingy which is basically a slideshow of dolphin pictures from Flickr and a clock, so you can keep track of how long you've been staring into its wonderful magnificence.
For those interested, the page itself is pure HTML/Java Script with a little CSS for layout. Image grabbing is handled by a PHP script which interfaces with the Flickr API and grabs a dolphin image.
Feel free to take a look at the source for the page, it's relatively simple but elegant. (Heads up: I tried to make the page data size as small as possible, so there is no spacing to speak of and I've embedded two base64-encoded images directly in the page for the loading animation and also a filler background to make things work.)
