Jean-Paul put together a nice Pandora widget for your WordPress sidebar. Pandora is a free music service that creates stations based on your feedback. The displays your favorite songs, a link to your profile and a little form to encourage others to sign up.

Allyn wrote a plugin called Shire Reckoning a while back to display the current date in the Shire Calendar, a date system of Tolkien’s invention. Now it’s even easier to use thanks to Allyn’s calendar widget.

From Velvet:

I created the Twitter sidebar widget for WordPress because I wanted something more customisable than the badges issued by Twitter. If you know your way around CSS you can style it yourself, otherwise it will keep the default styling of lists in your sidebar.

You may think I’m nuts, but I think you should reserve the driest spot in your hollow log this winter for this Squirl widget. What is Squirl? No, it is not a spelling reform campaign.

Squirl is a new way to catalog, organize and share your books, records, movies, comic books, stamps, coins, or practically anything else, and meet other collectors who are as passionate as you.

The widget proudly displays your collectibles on your blog.

What a wonderful toy! This widget sets up a database table that holds user-contributed definitions for words. The widget displays a word and its definition, hyperlinking each word in the definition to that word’s own definition. If a word is undefined, it instead links to a form that allows the user to define the word. I can see this being a ton of fun.

The demo is Dutch. The first person to set this up for English or any other language should leave a link here in the comments!
