Well, a picture standard is a first step.  But, I don't want to look at
pictures created by others, I want to interact with them.  I've
designed a first cut at a 3D real-time window system, called 5D.  The
visual part is 3 dimensions, real-time interaction gives the fourth
dimension, and sound and other interaction (such as
force-feedback joysticks) form the fifth dimension.

5D uses a Smalltalk-style object-oriented system to define visual
objects and their static and dynamic properties:  a box may be blue,
shiny, and have a sound inside it which gets louder when you get near.
Adding specifications for rendering via this or that method is
a minor detail under this method.  The system can support still-frame
or continuous motion, depending on how much rendering you're willing
to implement and wait around for.

The specification is available by e-mail.  It is 60 pages of nroff-d
output.
