I've been fooling around with some programming with Google homepage gadgets.  I think Google Pages will be a good place for me to host them for now.  Here's what I have so far:

Homepage Maximizer
This gadget simply removes the Google search bar at the top your personalized homepage.  I was already using the Official Google Mini Search, and the searchbar at the top was taking a lot of space.

FFXI Search
Per a request from a good friend, I also wrote a gadget to perform a search on ffxi.somepage.com.

Web Definitions
An AJAX based gadget that performs dictionary searches without reloading the web page.

Thesaurus
A gadget very similar to the Web Definitions gadget, but for thesaurus searches instead.  Results are loaded right into iGoogle.

Unit Conversion Calculator

Another AJAX based gadget that will perform unit conversions using Google Calculator.

Craigslist Search

Perform craigslist searches right on your iGoogle page.
