Introduction

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.

Motivation

Step 1: User-controllable fire art
Step 2: ...
Step 3: Profit!

Design

2πr is a blisteringly interactive large-scale fire toy. It is a central platform 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 octagonal platform 6ft in diameter. Around the edge of this platform are 16 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 lower than 3ft, a solenoid is triggered and a low flame is automatically produced in the corresponding flame effect, 25 feet away. And when the sensor detects an object passing over the emitter higher than 3ft, a second solenoid is triggered and high flame is produced from the same effect.

Community

2πr is made possible by Interpretive Arson and the community that surrounds it. Support is graciously provided by the members of Camp DDI and the help of numerous volunteers. In addition, we support the Burning Man community, which helped make everything possible by granting us funding and on-site support, as an honorarium project for the year 2006.
