interactive art installation - sonar, projector

I'm working with Martina Sprenghart (fashion photographer) to produce an installation for her latest work.

I'm using an arduino to read distance information from 2 ultrasound sensors, interface with a slide projector and send ripples across a tank of water. The projector shows images from Martina's latest work by passing them through the rippling tank of water. The size and frequency of the ripples are dependent on people's movement in the space.

Some pics of project in development here:

The exhibition is in in the Mall Galleries: 17 Carlton House Terrace, London, SW1Y 5BD http://www.mallgalleries.org.uk/. Please come along on the 10th. Feb. between 15:00 - 20:00.
