I admit that I am the world's worst at keeping this updated.
I have been busy with the blasting issue in Tennessee. See for more details.
Also, check out my github account over at Github.com/Sophrinix.
I track a few projects and in theory maintain a branch of ruby-x3d. One day, this library will be a full implementation of the X3d standard in ruby!
When I am not busy with the two aforementioned issues, I find myself working on my iPhone applications.
When apple finally approves of my apps, I will have an update.
Hopefully, this page won't go another 7 months without being updated. :-)
