The three celled 3DO Pyramid (above left) has a four colour graphic to give a three dimensional effect in the sky. Many different permutations are possible and more cells can be added.  A seven celled twist and a five celled appliqued face are also shown.. All 3DOs fly easily at a very high angle, similar to that of a delta, and in a wide range of winds. To see other examples click on the 3do gallery button.
