This would be great for connecting up to a CI server or monitoring system. If a build breaks, flash red or maybe if the site goes down go to solid red.
For instance, you can use yellow for "warning/important" level and red for "critical" level, and lights-only for staging environment and light & sound alarm for production environment, for instance. Pretty expensive, though.
I understand that sentiment is popular on HN, but not listing prices is pretty standard for B2B. At least in Japan (where Patlite is based), most businesses will not discard a potential vendor just because they don't list prices on their webpage.
You don't want to work in a room with a flashing light.
Also, there are tons of colored LEDs that integrate with CI systems already. And it's something you can whip up with an ATtiny or similar in about 10 minutes anyway. (Hint, your VGA port has an I2C pin on it.)
