Ai Weiwei and Olafur Eliasson have launched a new collaborative project entitled “Moon” that invites viewers to “mark the passage from nothing to something and from thinking into doing” by making their mark on a giant digital moon and

The collaborative online platform was launched on November 9 during the Falling Walls conference in Berlin at which Ai Weiwei and Olafur Eliasson were guest speakers, Ai Weiwei via live video from his studio in China and Eliasson on stage at the Radialsystem.

“Turn nothing into something – make a drawing, make a mark. Connect with others through this space of imagination. Look at other people’s drawings and share them with the world. Be part of the growing community to celebrate how creative expression transcends external borders and internal constraints. We are in this world together,” says Ai Weiwei and Olafur Eliasson

“Moon” participants are instructed to find a place on the moon where you would like to make your mark, click to draw, assign tags to your mark and click the tick to submit. Mark makers are encouraged to respond to other people’s marks by making your own next to theirs, to begin a dialogue, and share their favourite marks via Twitter or Facebook.
