I went to the Eastern State Penitentiary in Philadelphia for their
Halloween show, they too had this 3D section. In addition to the 3D,
they also had laser display and an optical illusion tunnel. Will be
nice to have these done at the Physics Fair here. I found the laser
device is now being sold at Edmund Scientific.
