Ready to be hypnotized by the undulations of the Great Ball Contraption Serpent? This GBC module created by Jean-Marc Détraz and decorated with vintage colors is composed of several oscillating platforms. As the gears rotate, the platforms tilt forward or backward to collect or push the GBC balls to the next platform. The jerky movements of this LEGO machine give the impression of watching a creeping reptile slithering across the floor. You should be able to easily replicate this LEGO marble run machine from the numerous photos and the video available on Planet GBC.
