i'd just like to mention that the true origin of the swastika goes back millenia to the fertility rites each year in norse times.
the swastika comes from the 'swazelstik' which was the shape it is now. at the end of each of the four branches was built a 'smoky' fire, and the swazel was then placed(balanced) on top of a pole(which is now the maypole)and spun around. the resulting smoke pattern(four trails of smoke) intertwined in a spiralling pattern that is very similar to the double helix of human d.n.a. and a pattern that is commonly found in nature.
