The synthesizer that started it all...The Moog System Modular Synthesizer, represented here by the widely-known 55 model.

In 1964, Dr. Robert Moog showed the first of his modular synthesizers to the world, and over the next few years transformed the emerging world of electronic music synthesis by taking a keyboard-based approach to the controlled manipulation of electronic sounds. The Moog 55 and subsequent models made their way into universities, concert stages, and recording studios around the world.

In a modular synthesizer, various electronic components such as voltage-controlled oscillators, amplifiers, filters, and envelopes are "patched" together in various ways by hardware cables, allowing the composer or player to a world of new sonic possibilities. Since the instrument is modular, various components can be swapped out, replaced, or upgraded to suit the needs of the musician.

This Lego-ified version of the Moog 55 has swappable black panels full of components, dials, and audio jacks that can be connected in various ways. Obviously, the elements are only meant to suggest the qualities of the various modular components, and the owner of this set could customize the cabling and dial and jack placement to their heart's content.
