Not a great deal really. Currently looking for programming jobs in the video game industry and working on various projects, mainly the WGD-Lib library and various simple demos that use it.
The main one being Wii-fly which is a multiplayer flight sim type game controlled using wiimotes. There are some problems with the windows version (ie wiimotes dont work yet) so I have not uploaded a binary for it. Follow the link for more info and screenshots...

There is also a newer version of Treegen in the works that uses the latest version of the library. This version has more options for creating a wider variety of trees for games. Also it is much easier to integrate in to other games that use the library due to its modular design.
I'll try to update the WGD-Lib website soon to have information about all this stuff.
