More fun using Tempest for Eliza and a photodiode

You don't need a AM radio to use Tempest for Eliza. You can also use a photodiode and an amplifier to make your monitor play music! You basically convert sound to light and then convert that light back to sound... pretty neat stuff. See YourMathsTutor for a diagram and instructions on how to build your own.
