Beast is an elaborate violin with many different lighting features (including chasing lights and an ultraviolet tube under the spine), a Japanese agate carving in the scroll (through which a laser shines), and a built-in low-power FM radio transmitter with status indicator lights. It combines a very large number of options and controls with a design that is visually very light and open. This violin's name comes both from the little monster face on the carving in the scroll, and the fact that it was a real "beast" to make because of the need to squeeze so much circuitry into very little internal space. Beast demonstrates E. F. Keebler's skill at designing ergonomic and logical control layouts.
