ERNO Rubik, creator of the 3-D combination puzzle, is telling Shanghai the story of the infuriating toy that had to be twisted and turned this way and that to produce the correct finish.

It went viral in the 1980s in the days before going viral had even been heard of. And it could take an age to solve.

He is presenting its history through his exhibition “Beyond Rubik’s Cube,” during which visitors can see other masterpiece creations.
