Der Computer-Monitor als Mittelwellensender. Tempest for Eliza: "All electronic devices send out eletromagnetic waves. so does your monitor. and your monitor does it all the time. and at very high frequencies. high enough for your short wave AM radio. all you have to do is display the 'correct' image on your screen and your monitor will emit the 'right' signals. Tempest for Eliza displays pictures on your screen. one for each note in the song."
