I have created a custom voice file for GPS units with a stylized voice in the fashion of GLaDOS, the charmingly creepy antagonist of the game. That's right. You can now dutifully follow directions from your GPS unit all the while wondering if the next instruction will lead you to your GPS-planned doom in a car wash retrofitted with flame throwers and sawmill blades. Take a look at the video below for a very quick sample of the voice.
