Overview
Many truly great ideas come from three dimensional (3D) thinking. With 3D thinking, you relate your problem or opportunity to other ones which, although on the face of things may not seem connected, but deep down share similar characteristics. George de Mestral noticed the way that burs stuck to his clothes, after riding in the country. When he looked at them under the microscope he found that each one was surrounded miniature hooks which had caught on the material. This gave him the idea of attaching similar shaped hooks to strips of fabric (Velcro) - and the rest is history.
