Trilon

|
A trilon is a box in the shape of an equilateral-triangular right prism that is occasionally used on certain game shows to hide information until needed. The squares on the old Concentration game board, the categories on Pyramid, and the letter squares on the old Wheel of Fortune letter board used trilons.
The trilon (or trylon) and the perisphere were the central structures of the New York World's Fair of 1939-1940. The trilon was a 700-foot spire. Built in Flushing Meadows in Queens, New York, both structures were subsequently razed.
The trilon is mentioned in the Groucho Marx song Lydia the Tattooed Lady.
One should not confuse trilon with the number one trillion.
