  If you're curious what a "real" performance of this piece sounds like, here's a great version: https://www.youtube.com/watch?v=9QKnUzyh84U

  For me this transitioned the piece from "a fun academic exercise" to "an amazing piece of real music"

  Also includes a great explanation of the piece musically.

  Does anyone have a display from this vendor? I’m curious whether my display code https://github.com/dmd/clack which was written for the Krush Flip Clock works. It’s also rs-485.

  It doesn't work as well, but I tried this on split-flap display: https://milek7.pl/.stuff/splitflap_clap.mp4

  Flip disc display version of that hard disk drive noise music you may have seen.

  Very cool.

  tl;dr the author created new art [0] from flip-dot boards [1] that emphasized their sound, rather than pixel art. Some fan encouraged the author to gear the work to imitate Clapping Music [2], a 1972 clapping composition inspired by flamenco.
