title: Optic Mirage
aka:  parabolic mirror mirage,  3 D illusion

Description:
Two nested parabolic mirrors project a 3 dimensional image that floats just above the hole in the top mirror.

Question?
   How does the location of the object relate to the location of the image?
   Why are there two mirrors?
