    Love to laugh out loud? Then you may be the perfect candidate for laugh, a global project to create the first piece of art in outer space using the International Space Station's (ISS) newly acquired 3D printer. While transforming an emotion into art may seem a little far-fetched, Eyal Gever is known for his gift for combining art and technology to make 3D sculptures from life-like digital simulations based on moments in time.

He was offered the project by Made In Space Inc. that specializes in manufacturing 3D printers for use in microgravity. Realizing the enormous responsibility of being the first artist whose work is created in space, Gever wanted to choose a subject with universal appeal - something that would be appreciated by everyone regardless of country or culture. After considering several ideas, he settled on creating a 3D human laughter, an emotion that is loved and treasured by all of humanity.

People wishing to send their giggles to space have to download the laugh app and record their best laughter. The app turns the sound file into a 3D model that resembles a burst of light or a "laugh star" which can be shared on social media and also rated by other app users. The laughter that receives the maximum number of likes and tweets by December 31, will be declared the winner.

The artist will then transmit the design file of the winning laugh to NASA's Operations Support Center in Alabama, where it will be uploaded via a satellite link to the ISS. The astronauts will print the 3D sculpture of the "laugh star" and release it into orbit (轨道) where it will float among real stars for ever, or at least until discovered by aliens!

Though this is the first time Gever is creating art for space, he is no stranger to unusual projects. His "Water Dancer" , a projection of light on a water wall, features a dancer whose body disperses(伸展) as she moves. The recently sculpted "Piece of Ocean" , created from a realistic computer simulation(模试验) of ocean waves, bears an impressive resemblance to the real thing.
