I am always trying new things here, feel free to e-mail me if you see a problem.
I copied some sample VRML worlds from the book "The VRML Sourcebook" by Andrea L. Ames and David R. Nadeau of SDSC. If you have a VRML browser, try the hut , truck , submarine , or rocket VRML world!
I am also working on a prototype site of my own. Check out my downtown scene
I have been working on a Military Base world.
YOU ARE WARNED IT IS 1.4MB
  
Military Base 7
More experiments:
One Ball and 9 balls.
They are really spheres in VRML.
