Here are five Anish Kapoor artworks you should know.

Sky Mirror, 2001

Kapoor turns the world upside down with hisSky Mirrorinstallation.

The original public sculpture was commissioned by theNottingham Playhousein England, but Kapoor also created a larger version.

Marsyas, 2002-03

Kapoor collaborated with artist and engineer Cecil Balmond to createMarsyas.

Marsyasreferences the ancient Greek satyr of the same name who played a double pipe instrument known as theaulos.

Just as loud music demands attention, Kapoors huge red sculpture commands notice.

Kapoor tried to visually emulate the effect of music by creating a piece on a huge scale.

The pyramids are the size they are because they are.

Scale is a tool, a tool of sculpture.

Because of its kidney shape,Cloud Gatehas come to be affectionately known asThe Bean.

At first, Kapoor wasnt a fan of the public-given nickname and called it completely stupid.

However, over the years, the artist came to embrace the moniker.

The violent visualization is intended to unsettle the viewer and invite them to remember past and present world conflict.

It features a giant, spinning whirlpool of black water that appears to spin into a seemingly bottomless pit.

By manipulating an everyday material like water, Kapoor explores our preconceived assumptions of the physical world.

Descensiondestabilizes our experience of the solidity of the ground we stand on, says Kochi-Muziris Biennale.

It builds on Kapoor’s concern with non-objects and with auto-generated form.
