<h1>Convergence is an interactive installation which invites the audience to create music and an interlinked visual display of geometric patterns. This is all achieved through the manipulation of a few <a href="http://casperelectronics.com/wp-content/uploads/NovaDrone/HomePage/NovaDroneV1.3_schematic.png">simple electronic oscillators</a>.</h1>

The installation presents the public with a circular control station monitored by a small camera hanging directly above it. Manipulating the controls triggers oscillators which are represented as sound from within the station and light from the light fixture on top of the station. The light is then captured by the camera and projected on the screen. See the second video below (the horizontal color bars) for an example of the video output of the camera.

<strong>Background:</strong>
This piece is an evolved version of a musical instrument I have recently designed called the <a href="http://casperelectronics.com/finished-pieces/nova-drone/">NovaDrone</a>. There is extensive documentation of this project <a href="http://casperelectronics.com/finished-pieces/nova-drone/">here</a>.

The NovaDrone is a sound and light synthesizer which uses analog oscillators and pulse width modulation to create interlink sound and light.
This technology will be implemented in Convergence to achieve lighting effects similar to the video below.

The video below shows a complex visual display which is created by holding a digital camera up to the light source. This effect will be utilized to create the projected visuals for Convergence.
