In 2007, Valve Software released Portal, one of the most enjoyable and creative video games of the year.
But you already know that.
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.
Note: The GLaGPS voice file currently only works for the excellent Garmin Nuvi (and possibly StreetPilot) units, but a TomTom voice file is in the works and should be available soon. Owners of Magellan and other brands are out of luck. If in doubt, check the GLaGPS Hardware Compatibility List to find out if your unit is supported. If it is, follow the link below to download it.
