Viewing in 3D

Some of the sculptures above are shown below in a manner that allows three dimensional viewing. Two viewing techniques are offered:  The first requires special glasses, but the second requires only that you train your eyes. 

Technique 1: Single images are meant for viewing through "anaglyph" 3D glasses. These have a red lens for the left eye and a blue lens for the right.  You can purchase the glasses for a few dollars.  They can then be used to view anaglyph images that abound on the web.  I purchased a pair of clip-ons to view 3D images that appear occasionally on NASA's Astronomy Picture of the Day. (You can find more NASA 3D-images by Googling APOD 3D images.) 

Technique 2:  Pictures below that are side-by-side will create a 3D illusion without any apparatus once you perfect  "cross-eyed" viewing. Center yourself between the two images, and gradually cross your eyes. The two images will drift toward one another. When they overlap, concentrate on the overlapped image until it appears in 3D.   It often takes some practice. Moving closer or farther away from the screen may coax the illusion to pop out.

If you have trouble, try this trick: Place your index finger near the screen just below the image pair and focus on your finger while drawing it toward your face.  You should become aware of the two images gradually approaching each other behind your finger. When the pair of images overlaps, shift your attention to this coalesced image and adjust your focus until the 3D illusion appears.
