Back at Netscape, one of our early internal tools was Tinderbox, which ran continuous builds on multiple platforms and cross-referenced build failures with check-in logs to pinpoint who's fault it was. (It was called "Tinderbox" because when it turns red, "the tree is on fire".)

This was inspired by an earlier hack used at SGI that was hooked up to the building's PA. When the build broke, a text-to-speech system would announce it to the world. "The build. Is broken. Terry. Broke the build."

Public shaming works even better than you might expect!

Who broke the build?

Retaliation is a Jenkins CI build monitor that automatically coordinates a foam missile counter-attack against the developer who breaks the build. It does this by playing a pre-programmed control sequence to a USB Foam Missile Launcher to target the offending code monkey. Check out the video to see Tom take one in the back of the head all because of a missing semicolon!
