When Edward Harvey invented the original squares and triangles that snapped together to help the formation of cubes and prisms in the early 1970's, he had little idea that over 40 years later children around the world would still be enjoying the innovation. Edward's son, Ronan realised the potential of this wonderful and unique tool, and marketed it to the education fraternity. This innovative tool has grown in popularity and has helped and inspired millions of children around the world.
