Has anyone actually made a Chaosphere model? I'm working on one at the moment and wanted to see if anyone had some tips on construction. I'm using A styrophoam sphere, dowels for arms, and foamboard tetrahedrons for the arrowheads. The only way to position the arms correctly (as far as I can tell) seems to be by making a cube around the sphere and marking the vertices with pins or something so you get the right angle and spacing. Anyone have any ideas? Has anyone built theirs differently?
