From Moco Art:
Vicki DaSilva uses tube lamps to create photography based on light graffiti. DaSilva uses this medium to create site-specific installations loaded with socio-political commentary. The single frame time exposure light paintings are made by moving the lamps either by hand or along tracks to create fields of light. Her current show of work, Reverb, features photos based in an abandoned silk factory. The photo above is in reference to the Chinese artist/activist, the pale yellow a nod to the Jasmine Revolution.
