You might not realize it, but VRML lives on, with Java-enablement and 
extensions, in MPEG4 in the higher level profiles.
I wondered where it 'went' for a while and then read all of the MPEG4 
standards, and implemented the file format and scene description, while 
working for an MPEG4 video encoding company a couple years ago.  VRML is 
the basis for the generalized scene description language which is 
encoded as a hand-packed bit encoded (a la Huffman) specific-schema.  As 
long as you never extend it, that's somewhat ok, although you end up 
with a lot of specific parser code corresponding to everything.

That's not to say that anyone has really tried yet to create a complete 
MPEG4 player.  MPEG4 is truly the kitchen sink of "standards", er 
specfications.  I like it and am horrified by it at the same time.

That it includes VRML, Java, and a file format based on Quicktime is 
very interesting I thought.
