A number of works in TO THE LIGHT position both artist and viewer as agents of change. For example, a series of instruction pieces written especially for the Serpentine Gallery can be completed physically or mentally by the viewer, while the large-scale installation AMAZE transforms the viewer from the observer to the observed. Ono also presents #smilesfilm, a worldwide participatory project that will be exhibited at the Serpentine Gallery and encourages participation online. Conceived as a way of connecting people across the world, the project invites people to upload and send images of their smiles by hash-tagging#smilesfilm, creating a global string of smiles covering the planet. Working as an artist, film-maker, poet, musician, writer, performance artist and peace activist for over five decades, Yoko Ono has influenced generations of artists and received numerous prestigious awards. In her prolific career, she has embraced a wide range of media, defying traditional boundaries and creating new forms of artistic expression. Born in 1933 in Tokyo, she is a pioneer of conceptual art and her work has been presented internationally in major exhibitions and performances. TO THE LIGHT at the Serpentine Gallery is part of the London 2012 Festival, a spectacular 12-week UK-wide celebration featuring internationally-renowned artists from Midsummer's Day on 21 June to the final day of the Paralympic Games on 9 September 2012.
