Crystal rocks

Daan Roosegaarde's interactive light installation, "Crystal", encourages people to share stories and light up the dark.

Creating a sensual relationship between people, technology and light, Daan Roosegaarde’s "Crystal" project encourages interaction to light up the dark.

Dutch designer and artist, Daan Roosegaarde has created a "digital campfire" allowing people to share stories of light. The interactive light installation, also known as "Lego from Mars", is made up of 700 small LED rocks, which light up when people interact with them.

Each crystal is made from a unique salt, which grows and transforms into a perfect geometrical shape around each LED light. Charged via a power mat on the ground, the crystals light up once touched or moved by interacting visitors.

People can write letters or icons to share stories in a very public way, says Roosegaarde.

The Dutch innovator believes that sharing is the new caring and encourages visitors to keep crystals and use them for other purposes, such as futuristic pieces of jewellery.

A permanent version of the crystal light installation will be placed in the historic area Strijp-S, in Eindhoven by the end of 2013.
