If you are into office warfare then surely you must have heard about USB missile launcher's. I found that now you can control your Marks and Spencer USB Missile Launcher on Linux and potentially other platforms that support python and libusb.

Requirements:
1. python (>=2.3)
2. libusb (>=0.1.8)
3. pyusb (==0.3.1) python module with patch
4. urwid python module

Scott also developed automated sentry mode which uses webcam and motion to have automated aim and fire capability.

I wouldn't be surprised if someone comes up more dangerous payloads. Fascinating technology.
