@TOOGAM : I guess misleading naming convention all round; I'm almost sure that the origin of the symbol lies in Hindu culture and the rest of the "similar" structures were self proclaimed "variations" of Swastika. I would be interested if someone can point me to a historical textbook from a non-hindu origin which mentions swastika and the reason why it was called so...

@DoktorJ: I'm an Indian; the 3rd is not a swastik, at least not in the sense the word "swastik" was associated with Hindu culture. The Carlsberg website specifically mentions "The Swastika is an ancient symbol of prosperity and goodness in Sanskrit" and I'm pretty sure there is only a single way to re-present Swastik; there is no "left-hand" swastik.

It's worth noting that the first and the second images are "Swastika" but the third one isn't.
