A shadow cloud is a 3D object the consists of multiple shadow-casting elements that appear to be randomly arranged. However, when the shadow is cast various images appear. Drzach & Suchy have created a shadow cloud that casts religious symbols, perhaps a comment on how interconnected we all are, or how these ideas ultimately exist in the same space (we are all on different sides of the same cube)?
Watch the video below to see the icons appear.
