Post# of 63700
while working at Eli Lilly Science Labs.
The director of the science dept was given
a travelling demonstration of laser holograms.
the 1st ones were inside a box with a viewing hole
of a chessboard.
You could move your head to view the side of a chess piece etc.
The director in his 60's exclaimed "Oh to be young again"
so excited over the new technology. He shared it with all us employees.
