Anish Kapoor - Concrete Piping Machine

Anish Kapoor is a celebrity and there's no need to introduce him. He has several works exhibited around London and wins ever growing number of prizes each year.

However I didn't know that last September he had an exhibition at the Royal Academy.

He created a machine (well, it's a pipe, connected to a computer) that creates formed material. The result is this endless spaghetti (let's consider it a spaghetti for now) which covered the whole floor of the gallery.

Royal Academy went further than calling it spaghetti:
[...] "using a computer programme similar to those employed by architects, a technician translates them into instructions that guide the machine. The process is simple: liquid concrete is shovelled into a hopper, from where it travels along a plastic pipe to be extruded in long, intestinal coils or short, turd-like lengths that accumulate to make up different forms; so far there are pyramids, nests, boats, triangles, ovals, lattices, spirals, beds, cubes and cylinders. The texture of some is dry and crumbly, while others appear liquid; some are dark grey, others spotted with white blobs of the polystyrene added to lessen the weight."
