This is pretty neat, ETM: Exploration Through Motion is an interesting view of a once static asset. A team of students from the Philadelphia University created this as their final project in Design 1. Together, they took the Thomas Moran painting “Grand Canyon of the Colorado River”, and made a 3D laser cut map diorama of it.
Turning a gear in turn turns a series of other gears that steps down the speed and ups the torque significantly. This in turn raises internal cams, which in turn raises a base layer of dowels that finally, raises the laser cut landscape. At first, I wasn’t sure why all the gears were necessary, I thought it was only for looks, but it’s actually quite a needed gear reduction in order to get the torque necessary to lift the heavy map.
