Resources for The Geometer's Sketchpad

I have been keeping a list of resources for the Geometer's Sketchpad that I have been giving out at workshops and have posted to the OSAPAC Learning Objects Repository (where it is currently in the top 10 downloads). There are two problems with it:

• it goes out of date
• I am the only person who adds to it

To solve this, I have posted the document as a wiki page. Please feel free to edit it and add your favorite resources.
