Hi everyone! Blinkenlights is a fun side-project app I made to be able to quickly see the status of anything you can dream up. I am obsessed with blinking status lights on hardware devices, so I used that as inspiration for a status dashboard UI. The app uses an open JSON protocol to drive the lights, and it's defined here:
http://blinkenlights-api.jazzychad.net/spec.html - the app comes with several example lights and registries for the S&P 500 stocks to show their change during the trading day. But you can create your own using the protocol above, and if you want you can contribute to the community registry so that others can use your lights. I also added the ability for people to manually add registries (e.g. if a company wanted to publish a list of lights internally for business-related statuses). Give it a try! I'll be adding more types of output displays over time.
