Shaun was amazing and managed to put together a working interface using my collected explosions clips. He used Max/MSP and made a patch where the video clip is played when the camera detects light value (in this case the lighter).
There are a few bugs: mainly that the clip resets itself and doesn’t play to the end if the light goes off and comes on again. Another issue is the health and safety aspects of using a naked flame. I doubt this would be allowed for the exhibition and especially not the Degree Show. As the flame is essentially a ‘detonator’ it might be a suggestion for viewers to use the light from their phones to trigger the explosion. This is in keeping with modern detonators - bombs being set off using mobile phones etc.
Most of all for this piece I want the explosion to be a surprise. I'd want the viewer to wander around the space with the light (much like Wile E. Coyote) and set off the explosion without any prior indication of what will happen.
