We have a birdman competition at the Melbourne festival( Moomba) and various characters leap off a ramp with odd wing forms attached.. into the Yarra River!  I have never done it myself but this form of mania attracts a certain amount of attention. I had a character leaping off a doghouse in a previous exhibition. I love these determined characters.In this case my hammer broke and in looking at the head it reminded me of astanding pose.. certainly a hammerhead with wings would indeed be taking a leap of faith.
