Easter Eggs
There's an intro to the chamber.
It's about how Chell escaped.
After it ends, text saying
"Chell: that was a massive mistake. i want to go back and test"
And after few chambers you will see Chell in a observation room with a button.
She will not do anything (chell doesnt have animations in hammer editor, more than walking and jumping floating, i think) and the button will press. A escape panel will open you will have to escape because after 20 seconds GLaDOS will turn on neurotoxin but not close the escape panel.

Nothing.
Trivia
Even if you stay in the chamber when the neurotoxin is ON, you won't take damage. This is because GLaDOS' Neurotoxin System got defected during the facility moving.
