The Pyros, Croman and Berry designs all use white
posterboard that allows light trespass through the
sides.  Although I did not do this myself, to keep the
peace in group settings, I recommend wrapping their
designs in black posterboard or painting the outside
with opaque black, so other imagers are not distrubed
during your flat making process. 

The key component is the milk white translucent
plastic. The milk-white plastic plates cost about
$22US, including cutting-costs, and can purchased from
companies in a U.S. telephone book under the category
"Plastics - Rods, Tubes, Sheets, Etc."  Suppliers
under that category cut the plastic sheets used in
advertising signage.
