mPrometheus for Mac, its 3-frequency color organ with moving lights. Offering automatic sensitivity settings, red, green, and blue lights flash with the music's bass, midrange, and treble sounds. Unlike most other color organs, mPrometheus determines the beat of the music and moves columns, rows,and clusters of circular lights in unpredictable patterns in time with the music. Ideal for parties, or music listening, the app employs the Mac's built-in mic.
