Last night I made a fake nuclear reactor control system and put it on the Internet for hackers to find.

It's a script implementing the absolute minimum of the VNC protocol to very slowly send a screenshot of a SCADA interface.

I'm logging any keys they try to type and mouse movements they make, and the next stage of the project is to use that data to drive a display in my living room, that'll look like an electronic cloud chamber (using e-paper)
