This has been posted elsewhere (http://forums.steampowered.com/forums/showthread.php?p=21935714), but I fear [SPOILER] in the title has put people off. Not a spoiler.

So Dawlight (and others) found a hidden dev commentary node inside Chapter 4, and it's by 'Adam Foster', creator of the popular Half-Life 2 singleplayer mod MINERVA. Video here. (http://kickurl.com/portalvideo)

The sound is, of course, SSTV. Below are the links to the THREE image files when decoded, as well as transcriptions of their content; I think it's a pretty cool Easter Egg, thanks Valve:


Portal 2 Announcement ARG (http://f.cl.ly/items/0F3S003n3w2x1W0L2X1o/Adam%20Foster1.jpg)


Created by people working on Portal 2
Intended for enthusiastic superfans
Budget of less than $100
Portal updated to include radios, broadcasting mysterious SSTV images
Certain images contained pieces of an MD5(?) hash of a phone number
Phone number led to an old-fashioned BBS
Estimated time to 'solve': 7 hours
Actual time to solve: 7 hours 16 minutes


Portal 2 SSTV Images (http://f.cl.ly/items/443A1d1D3B1C3G3X2O3h/Adam%20Foster2.jpg)


Analogue format used in HAM radio
Watching video of ISS SSTV with SSTV software running sound from laptop speakers unexpectedly picked up by microphone
Peculiar squeaking and beeping degrades in visually interesting ways
Photos of Valve whiteboards, equipment and anything science-related lying around
Finding radios in Portal made for fun meta-game - everyone could join in


Aperture Laboratories BBS (http://f.cl.ly/items/0v252h3j1f2X2Q2V3w2k/Adam%20Foster3.jpg)

Single analogue phone line in a designer's kitchen (phone systems in Valve office too modern)
Old PC running Linux, attached to a 2400 bps modem from 1987 (via USB to serial adaptor)
[?] to handle calls, custom PHP script looping through plot fragments and home-made ANSI-art conversions of Portal 2 artwork
Transmitted about 20MB of data in total
Phoneline constantly engaged!
Several spare modems in case one died - none did
SSH backdoor for updates and monitoring (possible to watch exactly what people were seeing as they dialed in)
Combined might of internets is terrifying

MD5 is correct (http://en.wikipedia.org/wiki/MD5).

Almost certainly mgetty (http://www.linuxcommand.org/man_pages/mgetty8.html).
