Playable Lego Harpsichord
With the exception of the wire strings, this instrument is entirely constructed out of LEGO parts–the keyboard, jacks, jack rack, jack rail, plectra, soundboard, bridge, hitch pins, tuning pins, wrestplank, nut, case, legs, lid, lid stick, and music stand are all built out of interlocking ABS (Acrylonitrile-Butadiene-Styrene) plastic bricks and related pieces.
And is playable.
Have a listen to this mp3 recording of the instrument.
