Mind Bending Paper Sculptures

How incredible are these scultures by Beijing artist Li Hongbo?

Hongbo magically tricks the eye with sculptures that look like marble but are really comprised of roughly 7,000 to 8,000 sheets of paper and weigh about 30 pounds.

Can’t believe that I just learned of him and missed his exhibit at Klein Sun Gallery in Chelsea, NY.

Anyone know where I can see his work live?
