Fun fact: The symbol in my user picture is a Celtic symbol usually called the Triskele or Triskelion (both terms from Greek for three-legged). Technically, it is a pre-Celtic symbol, but it was frequently adopted by the Celts, for whom the number three held mythological importance (e.g. triple deities and the three domains of Land, Sea, and Sky). —
