Eilonwy77 is a master at mosaics and patterns using LEGO. She was recently challenged to come up with the star and crescent symbols of Islam. While a six-pointed star is more commonly associated with Judaism, she says that in researching this she found some examples with six and eight-pointed stars rather than the more common five-pointed star. For the non-LEGO builders who may read this, the 36 degree angle for a five-pointed star is pretty much impossible* at this scale with LEGO pieces.
*Of course, that raises this as a challenge to all you builders out there.
