Unlike other 3D pictures you may have seen, the photos in The Big Penis Book 3D do not look distorted when viewed without the glasses. The Brain Factory’s technique is so subtle it’s hard to even detect the red/blue tint in many of the black and white photos, but when you put on your glasses the parts of interest leap from the page, not in flat layers as in old-style 3D, but as thick, fully rounded, touchable contours.
