InkQuencer is a step-sequencer that plays music based on camera input.
People can draw patterns on paper and then play back the pattern by holding
the drawing in front of the camera.
The program receives the images from the camera and draws a saled down,
32 by 30 pixel isometric version. On each beat from the metronome, the
scrubber runs through a new column of pixels and plays a sound if the pixel
is black.
