The kinetic sculptures created by Anthony Howe are nothing short of a miracle. You simply cannot wrap your mind around the fact that these creations are real. The magic comes from the fact that all the creations of Anthony Howe were first digitally modeled and only then wrought from metal. The resulting pieces of art are mystifying, entrancing, and sometimes even terrifying. For example, one of the earlier creations of Howe is an installation called “About Face”. It is a human face, pieces of which move from side to side, even if there is just a gentle breeze. However, most of his creations are mesmerizing, capturing your mind, as you marvel at their intricacy.
