Triptychos is a digital media triptych, transforming the realtime images from a video camera into an abstract graphical music score, and interpreting the score to play an interactive, algorithmic soundtrack.

The panes of the triptych expose the analytical process from left to right: video capture (left), thresholding and downsampling (centre), and graphical score (right).

The sound engine is a sophisticated sample manipulation instrument. Instructions from the score recall different audio selections, tunings and key intervals, and individual instrument voices play samples forwards or backwards, often changing direction and speed within a single note.
