Wormhole of David (Raelian Symbol)

The "Wormhole of David", used from 1991 to 2007, is a hexagram with the inner hexagon replaced with six spiral arcs to the center.
It was designed as an alternative to the original symbol of the Raelian Movement, which was a hexagram intertwined with a right-facing swastika. Western sensitivities to the swastika led the Raelians to adopt this alternative in 1991, although they have since officially returned to the old symbol, believing that education was more effective than avoidance in dealing with such matters.
