Melbourne Festival’s House of Mirrors has been extended for four weeks due to popular demand. The labyrinth has already had more than 30,000 people lose themselves inside its mirrored walls.

A House of Mirrors is a fairground staple – a gently disorientating and amusing sideshow. This is something else. Victorian artists Christian Wagstaff and Keith Courtney aim to unsettle you on a deeper level using steel and mirrors arranged into a geometric maze.

What seems clearly to be a corridor becomes a dead end, your own reflection appearing out of nowhere. What you’re sure is your own reflection turns out to be a stranger, equally lost in this kaleidoscopic panic dream. Be prepared to question your spatial perception for the rest of the day, long after you find the exit.

House of Mirrors has done the rounds, appearing at Dark Mofo and the Sydney Festival, fooling people all over the country with its disarming simplicity.

House of Mirrors is at the Arts Centre forecourt until November 19. Buy tickets at the venue. More information here.
