NOTE!This is a personal vision about forms and shapes, based on some known facts and artistic impression.CROSS VISION INSTRUCTIONS:In cross eye freeviewing the image for the left eye is on the right and the image for the right eye is on the left. You stare at a point about 1/2 way to the screen so that your eye's gaze is crossing at the half way point. Thus the left eye sees the correct image which is on the right. As you cross your eyes the image will go double. When your eyes are crossed the correct amount the middle images will overlap and be in 3d. The two outer images will remain and will be in 2d.A step by step Tutorial for 2D to 3D conversion can be found here: http://astroanarchy.blogspot.com/2009/04/neaic.html
