Although there have been many postings explaining how the SuperBowl 3D effect worked, I thought those of you wondering about the details may be interested in the following paper just published. Pulfrich published his paper in 1922 by the way. A Physiological Correlate of the Pulfrich Effect in Cortical Neurons of the Cat Thom Carney, Michael Paradiso, Ralph Freeman Vision Research (1989), vol29 no2, pp 155-165 The abstract says: "We found that placing a filter before one of the cat's eyes produced a temporal delay in the cortical response." From a quick skim of the paper, the size of the delays they find are roughly 11 and 29 milliseconds, for 1 and 2 log unit filters.
