This 120ft x 15ft  wire mural had silhouettes on the back and colour tissue papers attached to the front painted over as a huge abstract. 

In behind were colour lights. When those  lights were off, one could see only a gigantic abstract: but, when the room was darkened, and the rear light panels brought up, the mural was a sea of transparent colours with shapes of Canadian culture.

Regrettably there is no complete photo. The few fragments below (with gaps) are aligned from West (BC) to  East (PEI Confederation)
