460: Torus

Posted by wonko on November 16, 2013 in geometry |

Christmas is just around the corner, so I was thinking “wreath” shapes and stumbled across an astonishing torus made entirely of Tom Hull’s “Phizz” units: The structure is based on twisted units that combine in 5’s (a pentagon has positive curvature), 6’s (a hexagon has zero curvature) and 7’s (a heptagon has negative curvature). The […]

411: Phizz-based Stellated Icosahedron

Posted by wonko on October 25, 2012 in geometry |

The “phizz” unit designed by Tom Hull is a basic building block that can be used for many modulars: I thought I would start manageable, so devised a 30 unit ball, 6 faces each of 5 colours – total of 30 units. These are easy folding and have a positive locking mechanism so were a […]
