It hooks up hundreds of computers around the world to get them talking to one another at the same time to calculate acoustic and electromagnetic effects on the fuselages of fighter planes when they are in steep angles of attack.

FORBES: Sharing Power

It was the same guitar I had seen Alexis Korner playing, a double-cutaway semi-acoustic Kay, which at the time was a quite advanced instrument, although essentially, as I later learned, it was still only a copy of the best guitar of the day, the Gibson ES-335.
