Augmenting messages onto shadows

"As opposed to the 'on-demand' nature of digital memories we have become accustomed to, the 'Shadow Memories' bench ties this accessibility to the time and location of when a shadow is created. Users of a site-specific bench are encouraged to augment a video message on to the shadows it casts on the floor, using the image-recognition software on a specialist Augmented reality app. These digital memories can then be accessed by other people who also have the app, but only when the exact same shadow is reproduced a year after their initial tagging of the shadow. As the path of the Sun changes throughout the year, each shadow it casts is unique to that particular time, providing a constant cycle of new tags for digital memories to be augmented on to.
