Museum and art links is one good site to start your search. Or WebMuseum , or a specific one for the Museum of Modern art. They have truely captured the essence of what a web site should be, which is fun and informative, which gets people coming back again and again, and eventually, incidently, maybe buying your product. I give this site my own personal award as an example of a good approach. I can't find their free slide show screensaver anymore at their site.
Web Cams are fun.
You can tour the world or check what the weather and road conditions, such as at Snoqualmie pass, really are at a covered location, at a given time. Or check on Seattle area traffic . ClassMates is an on-line school reunion. See if you can find out what happened to that person you remember from High School. Its a long shot, but what the heck, why not give it a try.
