Shadowing, a project developed [in the old port city of Bristol, England] by Jonathan Chomko and Matthew Rosier, uses infrared tracking and triggered projections to replay the shadow of a previous passerby to the next person who walks under a modified streetlight. The design duo hopes that the reanimation of the city streets with ghostly time-travellers will be a playful experience for everyone, but also recognises the potentially darker side of the shadows.”
