Maximumm Exposure.
Maximum Exposure is an upcoming mod and (as far as I am aware,) the only mod for Portal 2 so far. Obviously as Valve haven't released Portal 2 yet, I can't completely make it but there are some parts of it in place.
Here is my ModDB: http://www.moddb.com/members/jalexinteractive. It has a small amount of media which does NOT reptesent the finished product. So far, everything that has been done is concept.
If you would like to get involved contact me here or on ModDB oyr YouTube or my website or whatever. All the nessecary links are on the ModDB page.
Maybe at some point I'll release the story basis.
Please leave feedback as to what you think, there are a few screenshots and a video but as I say it's all concept.
(P.S. I cannot access the Rules atm, it's a long and boring reason as to why but I have tried not to make this a "OMG COME HELP ME MAEK MAH MOD" post. Sorry if I am breaking any rules.)

I can count at least 3 that have existed for months off the top of my head.
(P.S: I enjoy being proved wrong)
As I say it's all concept anyway.
And I hope I will prove you wrong 
Oh and yeah. I'm sure there probably are more.
Opps I kinda went backwards there.

And I can count at least 4 that won't ever see the light of day.
