Hyper//Echo is a web-based “zone” where players are invited to explore the virtual space, and leave something behind — namely buildings and messages for other players to discover. Over the course of the 3-month exhibition, these artefacts gradually decay (buildings become ruins, messages appear as “broken links”) and become overgrown. Players are encouraged to return to “maintain” their and others’ buildings, as they eventually become irreparable if left abandoned for too long.
