Dreamachine

Murrayfield Ice Rink, Edinburgh, until September 25 Dreamachine takes its audiences on a kaleidoscopic, visual journey through flickering light and sound, all experienced through closed eyes, creating a shared multisensory experience.

It is inspired by a littleknown 1959 invention by artist-inventor Brion Gysin, whose homemade device used flickering light to create vivid illusions.

He hoped it would replace every TV set in America, with viewers of Dreamachine instead creating their own cinematic experiences.
