The gobos used for many of the projections were created by Moment Factory and manufactured by Rosco.
The designers chose to use custom made glass gobos in Martin 1200 projectors. But they were restricted to using an exact match of the official colours of the Winter Olympics and to design and produce them so they fit the triangular surfaces of the sails, with no image spill off the sails.
Rosco manufactured more than 40 colour glass gobos for this project, as well as nearly a dozen black and white glass gobos.
Anne Hunter, who supervised this project for Rosco, comments: "The interesting part was the colour scheme they sent us. There could be little to no fluctuation as we were told these were the official olympic colours - combinations and gradations of blues and greens.
"Gradations of different greens are sometimes difficult to achieve in the gobo colour mixing process. Greens can be a hard colour to hit. The combination of blues could also be difficult. however, because we have created different variations of cyan, magenta, and yellow glass for OEM purposes, we were able to pick the proper CMY combinations that would mix well to match the original art."
