	Create VRML From String Random Boxes

	Create X3D From String Random Spheres

When you click on the text in the scene, the boxes/spheres have new random locations computed.

There are many prototypes sprinkled through the X3D Examples.  Just searched for "<ProtoDeclare " there, found 1316 prototypes in 330 files, out of 3864 total X3D scenes.  (Gee maybe protos work after all...)

Contributions are welcome.  All of the public X3D Examples archives are unrestricted open source.  NPS recently shifted our BSD-style license for examples in the org.web3d tree to Web3D Consortium, thanks to Board of Directors review and approval.


Are we having fun with X3D yet?  8)

all the best, Don
