Turn your office into a disco with blink(1)
/Andrew's primary workstation is Linux-based. And in his post he describes how he "turned my office into a disco with blink(1) and Weechat". Weechat is an extensible chat client and has a "beep" function that you can extend to run any script, like say, one that triggers the blink1-tool commandline program. Really cool, Andrew!
