	I think all that is required is a differential rotation of a few
degrees. The actual number of degrees will scale the apparent depth and there
is a limited range of disparities until the stereo effect will break down.

	Try rotating one image (say the green one) 3 degrees relative to the
red one, about the vertical axis. Then try 5 degrees.
