This is Sebastian
Born in the fall of 2010, Sebastian enjoys alternately blowing tranquilly in the leafy fall breezes and rocking out to dubstep. He is just under a kilogram of sheet brass, steel screws, and brass geared servos. The culmination of a semester long course taught at Olin College of Engineering in Needham, MA, he is USB controlled and programmed for several dashingly symmetric dance moves.
This website details the design and challenges of creating "the beast" as he is so affectionately called (generally by those who dare tangle with his pointy petals).
