Speaking of Niceron and "Thaumaturgus Opticus," have you seen the 
Brothers Quay short animation film "Anamorphosis?" It's essentially a 
lecture on the subject with outstanding stop-action animation. It's 
on their DVD "The Brothers Quay Collection: Ten Astonishing Short 
Films 1984-1993" of which you can see more info about here:

Definitely worth checking out.
