Well, for one thing, I gotta wonder what you expect a bunch of people who've been trapped here for several months to be doing that they haven't already obviously tried - beat on the walls? That'd sure be effective.

[ Even if it worked, all it would get you is spaced. ]

But, to answer your question, when I'm not frantically trying to escape, I meditate here. It's a good place to re-focus and ground myself.
