GeomeTricks (Geometry Tricks) explores complex geometric structures based upon the geometrick Lbasic jointl; an interconnectable joint composed of four intersecting sets of three triangular prisms. The site includes instructions for assembling the basic joint, photographs of real-world geometrick sculpture, and interactive virtual 3D models. The geometricks are organized in levels of complexity to challenge visitors of all ages.
