Taiwan artist on Plato, scrap metal and history

Hsi Shih-pin, a Taipei-based artist, uses metals and calculations in his sculptures to depict the universe in its many dimensions.

A typical project for him involves first designing the blueprint on the computer and then getting a factory to make the components of his design before putting them together in his studio. He usually creates six pieces a year.

Now on display in Beijing is Circus Maximus, his first solo show, with 13 sculptures.
