The harpsichord is one of my favorite instruments. I love the tonality of the harpsichord sound and many of my favorite classical compositions feature the harpsichord as a primary instrument. I also happen to think LEGO blocks are among the greatest toys ever created. What does that have to do with the harpsichord? You would think nothing, but in this case, LEGO blocks are the harpsichord. That's right, following the documentation presented beyond that link, you could piece together your own LEGO harpsichord. Not feeling that ambitious? Read about the process of designing a LEGO harpsichord, then listen to the finished result. The blocks provide a rhythmic clicking you wouldn't get from other harpsichord building materials.
