This is Kristal’s latest model, a kinetic sculpture of a human head that opens up to reveal the inner workings of the mind. This is the second model in a series that she started a year an a half ago with ‘The Artist‘. Each head in the series opens up in a different way to depict a different aspect of the human mind.
All of the complex mechanics, as well as the light, are powered through the single crank on the side of the model. The electricity for the light is generated by using a LEGO motor as a generator connected to the crank. There is quite a bit going on in this model, through a series of 29 gears and 4 gear racks, to achieve all of the behavior. I try my best to explain how it all works in the video.
