Naum Gabo invented a whole art movement. Can you figure out what it is?

Kinetic art is "a form of art that depends on movement for its effect". Gabo is credited with giving it a name (often co-credited with his brother, Antoine (Natan) Pevsner; Naum changed his last name so the pair could be distinguished easier).

In 1919, Gabo created the first ever piece of such art, "Standing Waves" (also known as "Kinetic Construction" or "Kinetic Structure").

Just in case you want to question his credentials!
