Nope. Similar to what Wlodzimierz did, but this is just a quickie. CSG of a few
boxes, torus, spheres & cones; turned into an object pattern and tiled.
Besides, apparently his patterns are 2D too - I was truly stumped as to how he
managed a 3D-tilable Escher pattern ;) I'm not sure how he got more than 2
possible pattern values in his previous works, though...
