Call me an old fuddy duddy, but what on earth (or any place else, for that 
matter) is "4D space"?  And how do you "tie a plane into a knot"????   And, 
not that it really matters, but how many lenses do you need to record 4D 
space?  Oh, and one more thing:  could we please occupy the next hundred 
years or so expounding on a formula to derive the proper distances between 
the lenses to record 4D?

Just when I thought I was starting to understand the principles of 3D....  
YIKES!
