Moon
During it's flyby of Earth in August 1999,
the Cassini spacecraft tested it's instruments, and captured a series of
photographs of the moon. There is a small amount of depth on the
moon, but what makes this shot interesting is the layered effect of the
three images. Cross your eyes on the left two, and you will see the
resulting 3D moon float above the one on the right. It's a great
effect, even if not natural. For those of you with huge monitors,
click on the image to get a very large version- this image has great detail
in it.
