A system and method for processing at least one of an audio or video input for non-scripted light modulation of at least one light-emitting peripheral device (LEPD), said method comprising the steps of: recognizing at least one of the audio or video input from at least one first device (D1) and determining for at least one tagged event, at least one of a pixel color score, a pixel velocity score, an event proximity score, or an audio score, and commanding a trigger or control over a light-emitting effect of the at least one LEPD upon a threshold-grade score.
