We were invited back by South London Gallery to celebrate National Play Day 2016 the only way we know how - in audio! All the local children (and some adults) gathered round our microphones to record messages to their future selves. We turned these recordings into an audio time capsule and buried the voice messages in the gallery gardens. For Play Day 2017, we will return to South London Gallery to dig up our capsule and listen back to our advice given the previous year.
