You should check out www.supercircuits.com. They have a large range of "spy
stuff" which we have used in our performances.
Currently, in our piece "Vera's Body" which we perform again this coming
Saturday, we have a miniature video camera paired with one of their
miniature transmitters to give the audience multiple perspectives of her
body. The dancer holds the camera in her hand, pointing it both at her face
and occaisionally at the other dancers as she performs. The result is
projected behind her, so the audience sees both her performing and the view
from the camera. It works beautifully. In addition, we place our video
projector on the floor, so she sometimes is in front of the beam. Thus, a
third representation of her body in the form of a shadow, appears.
The transmitter is about 1/8 of an inch thick, and about the size of two
large postage stamps. Very small. The batteries to power it (8 AA) are much
bigger than the transmitter itself.
In any case, check out supercircuits. They are a great resource for fun
tools. Plus, it always seems correct to appropriate surveillance/police
technology for the purpose of art.
