This bench conserves the memories of those who have sat upon it in the past!
Designed by Joshua Barnes, this Shadow Memories bench records videos of the people who sit on it and save them to the Cloud. These saved digital memories are linked to the shadows which the bench casts, accessible only by an augmented reality app. Every hour of the day, every day of the year, and every season, the shadows the bench casts are set at a different angle, grow a little longer or shorter. These slight differences in shadows create real time-stamps, which a simple augmented reality app can detect. So precisely one year from the time you record your message, future visitors to the bench will be capable of viewing your message from the past.
