During
the meeting with the separatists, Wat Tambor fiddles with one of his
dials and makes a noise that sounds like it's from the Q*Bert arcade
game. Is this an inside joke, or mere coincidence?
This sound must be a mere coincidence. I made it using a vowel
generator in a synthesizer device called the Kyma.
