Figure 1: Left-Handed & Right-Handed Jitterbug Transformations. The animation on the left shows a vector equilibrium contracting from its cuboctahedral phase to its octahedral phase in a “left-handed” sense (associated with positive-mass electrons). The animation on the right similarly shows a vector equilibrium contracting from its cuboctahedral phase to its octahedral phase in a “right-handed” sense (associated with negative-mass electrons). As the left-handed and right-handed vector equilibriums progressively contract from their cuboctahedral phases to their octahedral phases, all of their corresponding triangles rotate in opposite directions.
