Mochord™ (“Mo” as in “Motor” often abbreviated to two letters as in “Motel” = “Motor hotel”, and “chord” as in the Ancient Greek prefix for stringed musical instruments, “chordophones”) is a musical instrument invented by Steve Mann in his childhood in the 1960s, based on spinning strings. This gave rise to the visual art form, Mochoid (“oid” as in “ellipsoid” or “cardiod”).  Mochoid    uses a LED light rope connected to a spinning base to create an interactive kinetic light sculpture that embraces the role of technology in connecting people and planet. Mochoid is a visually stunning display that evokes a sense of interconnectedness between:

  • Sustainability: the surrounding environment, climate, environment, earth, water, air, etc.
  • Technology, A.I.: virtuality, Internet, metaverse, and our modern digital age.
  • Society: human constructs like governance, law, privacy, security, trust and wildlife in our environment

Interact with Mochoid by setting your camera or camera phone on manual or long-exposure and hold your camera steady to capture one or more revolutions of the spinning LED light rope to reveal wave data as well as soundwaves.

    Steve Mann is a professor and inventor of High Dynamic Range (HDR) imaging, wearable computing, world's first smartwatch, and many other technologies. He is an LED light artist who invented, designed, and built the world's first addressable LED strips in the 1970s, which he used to create art installations and light painting tools. He is also the inventor of the hydraulophone (world’s first underwater musical instrument) and founded the Water-Human-Computer Interaction field. Together with his students, James Fung and Chris Aimone, as well as Trevor Coleman and neurologist Ariel Garten, Mann founded InteraXon, a Canadian company currently commercializing cyborg technology developed by Mann and his students. He received his PhD degree from MIT and is a tenured professor at University of Toronto, where he teaches Mersivity.
