Thanks for the reply!  Welcome to the List.

It would be interesting to see the exibit.  Other "replyers" suggest that
any color filter would work, must just be an optical illusions as you
suggest.  (a lapse in the processing of the two images.)

This brings to mind another interesting topic... those Magic Eye pictures
that when stared at for a while produces a 3D image.  Does anyone
know of a computer program that will create those images?  (I heard
that the images were computer generated.)

Sincerely,
