Polytope de Montréal
Polytope de Montréal was a media installation in the French Pavilion, which now houses the Montreal Casino. The installation included a sculpture, light show, and musical composition designed and composed by Iannis Xenakis, for the opening of the Ottawa Art Gallery following Expo 67. The piece is one of many polytopes (flat-sided geometric object, e.g., polyhedron) by Xenakis.
