Very interesting and useful site with a wealth of information about time, date, moonrise/sunset, timezones, etc.

A really cool site with essays about interesting things that happened in the past.

Damn interesting...

Joe Clark is an accessibility expert. This is his Web site. An excellent resource for people interested in accessible Web design.

This is a huge database of medical and biological images, representing 2,000 years of imagery.

Another interesting "map it yourself" service.

A very neat system, like Google Maps, that allows users to "create their own maps."

This is Microsoft's answer to Google Maps.

It is pretty darn good, especially the low-altitude "3-D" aerial images.

Very kewl.

It is a scanned library of original rare books and manuscripts. You can read Gallileo's first printed books, or view Blake's picture books as they were first published.

A collection of JavaScript scripts that implement DHTML and AJAX.

This has some pretty wild scripts in it. Think of it as a JavScript/AJAX version of Stu Nicholls' CSS Play site.

This is a very kewl AJAX interface to Wikipedia. It looks up entires as you type them, and helps you to quickly find pages.
