I reported this morning at SEW Blog;
Niall Kennedy has a good summary of Google's Universal Gadgets that can now be put on the Google Personalized Homepage, Google Desktop, Google Pages or your own web site using the Google Gadgets For Your Webpage collection of applets.
The Google Gadgets Directory has a nice amount of gadgets to quickly give you a ton of things to play with.
A WebmasterWorld thread notices how going to the directory without a trailing slash makes a difference on the gadgets you see.
