Architect celebrates Rubik’s Cube invention

Hungarian architect Erno Rubik is this month celebrating the 40th anniversary of his invention of the puzzle which made his name known throughout the world.

The 69-year-old has paired up with Liberty Science Center in Jersey City, New Jersey, USA for a special exhibition of the Rubik’s Cube.

Beyond Rubik’s Cube explores beginnings of the cube, showing its first prototypes – made out of wood and rubber bands.

It also houses the world’s most expensive Rubik’s Cube ever made. Created by Diamond Cutters International, it is an 18 karat gold cube set with 1,360 jewels, including white diamonds, green emeralds, red rubies, blue and yellow sapphires and purple amethysts, estimated to be worth $2.5m

Rubik said that after spending most of his adult life with the cube, he sees it as his eldest child.

While the cube launched in 1974 in Budapest, Hungary, it was initially not allowed to be sold outside of Eastern Europe, by order of the authorities in the Soviet Union. Since its international launch in 1980, about one in seven people have played with the famous puzzle.
