I love the tools on Bighugelabs.com
many are just fun, but some are really usefull and some are inbetween.
Some are nice to have and light up your day.
This one is a nice to have, if it could be used as a screensaver:
an everchanging photowall sorted by recently uploaded or user or tag or …. what setting you choose. It is really nice, and I would love to use it for my webblog, just like the changing photostream on the border, or to have it as a desktop screensaver.
Take a look and have fun:
