A 3D printed spatial object by Drzach & Suchy, based on shadow clouds.
A shadow cloud is a three-dimensional object, consisting of multiple shadow-casting elements semi-randomly arranged in three dimensions. A shadow cloud can be viewed as a generalization of shadow casting panels, but of course the basic idea is already present in the so called GEB-triples.

That is a brilliant piece and perfectly suited to the 3d printing process. I hope they make more, i would love to see how far they can take the idea
