As an example of the complex structures that one can build, albeit with
another program, I have found www.activeworlds.com, which seems to have
constructed large worlds and buildings, with lots of interaction. They have
their own programs, different from Adobe Atmosphere, but it gives an idea of
the complexity that these worlds can attain. Related to our purposes, for an
European health insurance company they had an avatar continuously giving a
conference every 10 minutes, with slides simultaneously projected in the
background, 24/7.
