In Bruce Sterling‘s wonderful novel Schismatrix (1985), the spaceship Red Consensus has an interesting feature:
The control room . . . had been designed by some forgotten industrial theorist who believed that instruments should use acoustic signals. . . . Bizarre at first, the sounds were designed to sink unobtrusively into the backbrain. Any change in the chorus, though, was immediately obvious. Lindsay found the music soothing, a combination of heartbeat and brain.
Now:
the Sheridan College Institute of Technology and Advanced Learning has created software that translates network and server activity into music. And, their IT department operators can interpret the music to detect problems in the system.
