So most of you will probably have a LCD panel in your office to display live status, such as build status, system monitoring etc. Now that is fine for large floors, but a bit overkill for many 2-3 person rooms and simple, discrete metrics. Also, I love physical indicators. Our Nagios system controls an old traffic light (from Ebay) using a Pi. It was fun to make, but also a lot of work. Ideally, I'd order a bunch of physical indicators and all my employees get one to hook up to their primary target.<p>So what do you have in your office to indicate live success and failure, apart from monitors? What works best for you? What was the easiest to implement?
