Portal received an innocuous-seeming patch today that turned out to be very interesting.
The patch introduced a new achievement, "Transmission Received." And the radios in the game have different colored power lights. It turns out that carrying those radios around to specific spots (26 in all) will allow you to hear some mysterious and hard-to-decipher radio transmissions.
But it gets even more interesting. Some brilliant folks decided to run the audio files for these new "transmissions" through SSTV programs, and it turns out the result is a set of poor-quality images, all bearing the Aperture Science logo. The images can be seen here: http://forums.steampowered.com...69218
Using the photos and an MD5 hash translator, the brilliant folks turned up a phone number from a region near Valve's WA headquarters. The number turns out to be a dataline for a BBS. Clues in the 26 photos help to reveal the login credentials for the BBS. The BBS access reveals a host of ASCII artwork.
Now, people have been working to clean up the ASCII artwork, producing some recognizable (and not-so-recognizable) images. The most recognizable things are the stick figures from the early Portal trailer and the egg-shaped turrets from Portal.
Someone has also cleaned up some of the "transmissions" from the game, and Kleiner and Barney seem to be audible.
Go boot up Portal and grab a radio. Join the party.And in case you want to cheat on the achievement, here are the radio "spots" to hit: http://forums.steampowered.com...69096
EDIT:Here's a text file showing the output from the BBS. Skip over the garble and scroll to near the bottom, where you'll find a hilariously horrible manual page detailing the viability of hobos, orphans, the mentally unstable, and the elderly as test subjects.
