(notes on) biology is an excellent stop-motion, hand-drawn short by Danny Madden, Jonathan Silva and Will Madden that won the 2012 SXSW Animated Short category. The first couple minutes are best described as the click-clack you hear while the roller coaster ascends its initial climb. A bit past the two minute mark, the lead car starts slowly peeking over the first drop. Once the elephant appears, WHEEEEEEEEEEEEEEEEEEEEE! Even the closing credits are fun!
