Brush Strokes v1.00
An audiovisual instrument with a drawing-based interface. Sound is generated in a manner similar to scanned synthesis, with two oscillators whose waveforms are obtained by scanning the x- and y-axis positions of the trail drawn by the user. The larger the gesture, the louder the sound, and vice-versa, when the mouse is not moving, no sound is generated.
The above processing applet demonstrates a slightly cut-down version of the visual part of the instrument (applet source code).
