2πr. Two concentric rings. The inner ring detects movement and translates it into fire exploding up from the ground on the outer ring. Presented without any visible theme, it is a blank slate for the user to perform upon. It seems to lend itself to thoughts of magic, though it could just as easily be seen as a tool for a performer, a conductor’s orchestra, or any number of other interpretations.

2πr is a blisteringly interactive large-scale fire toy. It is a central stage surrounded by a larger ring of inconspicuous flame effects – completely innocuous to onlookers – until a participant makes it come alive. It consists of two concentric rings: The inner ring is a 3ft tall circular platform, 6ft in diameter. Around the edge of this platform are 32 infrared proximity sensors placed at regular intervals. Each sensor is linked to a corresponding flame effect in the outer ring, which is 50ft in diameter. When the IR sensor detects an object passing over the emitter, a corresponding flame effect is triggered, producing a large burst of fire.
