There isn’t much you can do, because chances are it’s not the same group of people every time. But you can do some things to make yourself feel better.

What I did was wheel my chair out into the hall and sit in on their post-meeting meeting. I put a nice neutral/pleasant expression on my face, and looked attentively at whoever was speaking. I think it took three people before the speaker noticed me and kinda went “uhhh… are we disturbing you?” and herded everyone off.

Naturally the BOFH way is to arrange for a cable short so that the partition wall becomes live when people lean against it.

The other option is to wait until you get the conjunction of a critical problem and annoying people outside of your cubical… and talk to the people yakking away about the amount of money they are costing the company by distrubing you from your work to fix the problem. This probably works better for critical infrastructure systems like file servers or networks whose outage would affect lots of people.

I used to have a perimeter of upside-down drawing pins on my desk to stop idiots sitting on it when they were talking to the guy next to me. I’m sure with a little ingenuity this could be applied to partition walls somehow.

It’s an obvious-but-probably-stupid suggestion, but why can’t you move cubicles?

“Shut the fuck up, this isn’t a fucking conference room or your fucking cubicle, and I’m fucking trying to get some fucking work done, so just SHUT THE FUCKING FUCK UP!”

OK, put some little symbols like &*^%$!. Your employer is sensitive that way.
