As part of the Canada Day celebrations a children's activity workshop was organized for the construction of 3-D glasses. A large 3-D centrepiece was required to have something to look at. Mystus wrote a program to create shaded 3-D images from either existing 2-D images or specially taken two view photographs. Using this program a lage mural was assembled along the theme of Canadian Iventions. There is no limit on the size of the 3-D pictures we could produce using this process.
