The TexturedSphere example has a comment that it could do with ArcBall rotation (else there is reversal of controls) I have today posted a modified example including ArcBall control at open processing. I have also updated the sphere to be a retained shape in anticipation of processing-2.0. Unfortunately this means to view the sketch you will need to download it as openprocessing does not support opengl sketches of any kind!
Unfortunately it seems I am unable to see some (retained?) shapes in Processing 2.0a6. Not just with your example, it happens also to some (not all) of the examples that come with Procesing. No error messages, I just get a black screen.
That is kind of worrying, I've seen your GLSL stuff, so I wouldn't have thought it was a hardware issue, perhaps you should file a bug (although it might have already been fixed there have been a lot of changes since 2.0a6, although my sketch was exported from processing-2.0a6).
