Mobile marketing firm Somo has teamed up with artist and musician Yoko Ono, to bring an art project 45 years in the making to smartphones. The #smilesfilm app, developed in partnership with REVL8 Perfect Day, is intended to help gather footage of peoples smiling faces, from across the world.
Users can upload images of their smiling faces to Instagram or Twitter, to be added to the film, which can then be watched as an in-app video. 
“This is a delightful example of how tech can bring people together, for non-commercial gain, and how mobile really is making the world smaller,” says Somo CEO Nick Hynes. “At last, technology has finally caught up with Yoko’s vision.”
