I have searched through the archives and found a lot of discussion but no 
evidence that anyone has actually developed the mathematical function or 
even plotted a graph of the delay/density relationship. I did find a 
mention of a book entitled, "Foundations of Cyclopean Perception" by 
Julesz which purports to have some info about Pulfrich. If someone has a 
copy of this book, would you be so kind as to see if the author address 
the Pulfrich delay function?
