TO SEE THESE IN 3-D WITHOUT A STEREOSCOPE:
With index finger to your nose, stare at your fingertip while slowly extending it toward the mid-point of the images. As your eyes cross, the two images will separate to reveal a third one in between them. Relax and shift your gaze to this middle image, which should now be in 3-d. Further tip: make a zero with your hand and hold it several inches in front of you. Look at the 3-d image through the circle so the outer images disappear, then hold this position while clicking through the images.
