- We wanted this visible to everyone whether or not they were near a web browser or even a monitor.
- We wanted it to preserve the "red/yellow/green" status's xymon uses.

This article will be of particular interest to you if any of these apply:
- You have a stoplight that you wish could be controlled by a web browser.
- You would you like to learn how to safely control 120volt lamps from an arduino.
- You would you like to learn how to turn an ethernet shield equipped arduino into a simple web server to control outputs.
- You have a "red/green" monitoring system that you would like to have a visible, fun, hard-to-overlook physical component.
I'd sure love to have my own laser cutter. Please see the notes at the end for thoughts on how I would use one, and if you like this article, please rate it and vote for it in the laser challenge.
