Less than three
Less than Three is an installation consisting of a series of light beams that form a kind of network between two analogue intercoms.
When you speak into one of the intercoms you can see how the voice signal is converted into flashes of light that are visibly transmitted along one of the several possible routes through the network. When the flash of light reaches the other end, the spoken phrase is released and transformed again, from light to sound. The installation interacts by transforming sound stimuli into light, which is then turned back into sound again.
