  "Gordon Pask developed musical cybernetic systems that count as early
   cyborg hybrids. His 1953 Musicolour machine accompanied musical
   performers. As the performer or group played, Musicolour responded with
   lights and movement to the music would change, creating a sort of
   hypnotic effect for those who played with it. But if the performer
   became too repetitive and did not engage the machine enough, Musicolour
   would grow bored and stop responding—the first cybernetic art system to
   do so. [4] Pask also noted that while people trained the machine, it
   trained them back, creating a feedback loop in which performers felt
   like the machine was an extension of their minds and bodies.[5]"
