Art can be puzzling

And in this case, that's a literal description (hmmmm, where have I heard that phrase before...). The sculpture consists of 21 interlocking pieces made of brass, copper, aluminum, steel, stainless steel, cast iron, magnesium, titanium, tungsten, aluminum bronze and bearing bronze. Hidden inside is a one inch cube of solid silver or gold.

When fully assembled, this sculpture forms a beautiful three inch cube with softly rounded edges. It weighs 7-9 pounds depending on the metal composition.

Price is ~2k dollars, more if you want the gold ingot inside. I could never afford it, but I still think it's beautiful.
