John V. Muntean is a master of his art. Living near Chicago, Illinois USA, he currently works as a spectroscopist at Argonne National Laboratory, but despite that he (luckily for all the admirerers of his projects) finds the time to create the most breath-taking shadow-casting sculptures. 

The artist wrote on his website: "As a scientist and artist, I am interested in the how perception influences our theory of the universe. A Magic Angle Sculpture appears to be nothing more than an abstract wooden carving, skewered with a rod and mounted on a base. However, when lit from above and rotated at the magic angle (54.74º) it will cast three alternating shadows. Every 120º of rotation, the amorphous shadows evolve into independent forms. Our scientific interpretation of nature often depends upon our point of view. Perspective matters."

You can check out some of his videos below, but there are plenty more to see on his website.
