The large magnet structures in this video are built entirely from the same small repeating octahedron unit of 36 balls. The double width complete frame uses 180 of these octahedrons and 6480 magnets (36 x 15 x 12). The large triple width dome uses 225 octahedrons and 8100 magnets (36 x 15 x 15). I wanted to build the dome into a complete sphere but I didn't have enough (neo magnet) balls to finish it. It turns out that the magnets aren't strong enough for this to stand up, but a lighter version was made f
