Can you post the code you are having difficulty with ?

It may be that you have to replace void loop() with void draw()

here goes the code of the main sketch (the classes are not included here but you can download the code at the flight404 website)

download where ?  a link would help... it is not the loop/Draw problem though. i will check with the whole source then,

on this site  http://www.flight404.com/vj/exhibit.html you can download the source code. 

I cannot test these sketches as apparently they make use of a webcam and I don't have one. Do you have one?
Also you should activate your Java console (way to do it depends on your browser/system) and see if you have error messages.

I only tried the 'spheroid' example. This does work with P3D but not with OPENGL. I could get it to work
with OPENGL too, following the work around described at the bottom of this bug report: http://processing.org/bugs/bugzilla/1233.html.
