The way I would do your demo in OpenGL would be that every morph  
renders to its own off-screen surface, and when compositing, it would  
apply the non-linear transformation. This is now a standard  
implementation technique, except it usually is not used for  
projective geometry but for fancy effects (like the Genie effect when  
minimizing Mac OS X windows).

Mind I did not understand what you said in the talk, just commenting  
on the visuals ...
