While most may not think of the Rubik cube as a computer, the famous toy is a very basic analog computer.
The Rubik’s Cube has been around since the 70s. Invented by a Hungarian professor named Erno Rubik, his first prototype was made in 1974. When he had built his first cube, it took him a month to solve it. He got his patent in 1975 for his “Magic Cube”. In 1979, it was presented to toy fairs in various countries.
Tom Kremer, a toy specialist with a passion, convinced the Ideal Toy Company to pick this up as a product. The first thing they did was change the name from Magic Cube to Rubik’s Cube and launched it in 1980. By 1981 it was a world-wide craze. Through the years it has been reworked and made even faster. In 2017 they released the Rubik’s Speedcube.
