Nothing stops people from being creative but if you really want to take that idea in perspective, an art-inspired and solar powered cube would certainly be something.
Designed by Michael Jentzen, the Sun Altered Cube is a large structure that was made to create electricity to be used by its local community.
Solar cells are mounted on top of the cube, the collected power of which is delivered to two electric motors located at the two corners of the structure. These corners are able to rotate depending on the intensity of the sun.
The cube is intended to be situated in a public park and is painted the bold black and white stripes to emphasize its constant changing.
