Clockwork - K'Nex Roller Coaster

My 15th K'nex roller coaster, featuring a hubless ferris wheel lift. Music: "Where Civilization Once Lay" by Jeremiah Pena, one of my favorite composers. Check out more of his music at http://www.jeremiahpena.com Clockwork was partly inspired by Round About at Freestyle Music Park. However, this one uses a hubless wheel, meaning that there's no axle in the center of the wheel. This let me weave the track through the center of the wheel, creating a very twisty and compact layout. Construction took 4 weeks total. I automated the ride with a Lego Mindstorms NXT, just like all my other rides.
