Wearable Electronic Flash

Painting with lightvectors (a.k.a. "Dusting") requires a very powerful flashlamp. This is how I hold and aim the world's most powerful electronic flash (40kJ), which I configured as a body-worn tetherless apparatus. (I use it for architectural "lightpainting".)
Take a closeup look, or, if you have a fast net connection, you can load a larger picture of the lamp just before ignition, and during ignition.
