In the Cooperative Hub area near each of the chamber selection screens there is a small box that talks whenever you click on it. Aside from sounding like a turret, does the box have a purpose? These are the ones that light up purple as they are activated.

It appears to be a quote from the first paragraph of Moby Dick (thanks to Billare for figuring that out):
[…], and methodically knocking people's hats off — then, I account it high time to get to sea as soon as I can.
The full passage in Moby Dick:
You need to gain height, fall into a portal through the now exposed diagonally aligned panel, jump onto the blue gel and reach the exit.
Basically, from your second picture, just place a portal on that panel. The rest will take care of itself.
