Beep-it Deluxe emits a square-wave tone reminiscent of 8-bit video game music. A light sensor determines the overall pitch of the instrument, while a knob on the side can be adjusted to induce a warble into the tone for all of your sci-fi and rhythmic needs.
A demo video which explains all the functions and sonic possibilities can be seen here: http://vimeo.com/7939571
