Gabriel,

Imagine my surprise when I received the following post from the author of 
this game:

P.S. From Erlys: The GrenoVision Goggles were regular paper Pulfrich 
"glasses" like the ones given away with the purchase of CocaCola for the 
Super Bowl some years ago. Each eye had a different colored lens, or else 
one eye had no lens and the other was a brown color. Anybody still have a 
pair of these?
