There were two videos that were posted in random thread (I think). One was a first person view of a guy escaping a physics facility when something goes wrong, it uses some HL sounds, etc. He's carrying some device...
The other is a guy creating a virtual world for his girl who is in a coma to enjoy her brain in.
These were posted a year or two ago, if anyone knows what I am talking about I would really appreciate some links.
Thanks!
