Yeah- I clearly don't have my head wrapped around the whole dot pitch vs. dpi vs. real world pixels per inch vs.lpi
In my n00bish mind, if there are truly 120 dots (pixels) per inch, and there really are 60 lines per inch, then you would have a 2:1 ratio and be able to pull this off.
Nevertheless, I decided to go ahead and spring for a 25 pack of 60 LPI lenses from vuethru.com. It was only 40 bucks and I figure at the very least I'll wind up with some lenses to do some 3D photos with. If it does in fact work, I then plan on springing for a bigger sized lens, or attempting to piece several 4x6s side-by-side
