ANOI VASE by MORENO RATTI. 

Moreno Ratti's aNoi vase vessel is formed around a metal tube, using the Carrera marble disks to create different shapes up its length.

The stacking of rings is reminiscent of the Tower of Hanoi puzzle, invented by French mathematician Édouard Lucas in 1883.

The game consists of three rods and a series of disks – each with a different diameter – that form a cone shape when stacked on the first rod.

Following a strict set of rules restricting the way the pieces are allowed to stack, the user has to move all of the disks from the first rod to the third so they sit in size order, using the middle rod as an intermediary.

"You can create different shapes, depending on the order in which you have the rings," said Ratti. The rings measure either two or four centimetres deep, and each has a different diameter.
