This seems sensible, but I often notice fairly strong stereoscopic vision in woodsy mountains, looking at things such as 500 foot hills half a mile away. Which brings up a related question... I seem to perceive stereo lots better when looking at something that's generally green, like those woodsy hills or nearby bushes, than when looking at other colors. Is there a correlation between stereo and color, or do I just have an affinity for trees and bushes? --------------------- Paul Raveling Raveling@vaxb.isi.edu
