Back in the 80s did a similar thing with my mate to control lights for a disco in the school. We used triacs rather than mechanical switches and 8 channels of lights controlled by a port on a Vic20.
Worked great, until we connected it up to 500W stage lights (sometimes two at a time) and the triacs all melted!!! Add one huge aluminium heatsink and voila!
The super-duper improved version used a multiplexer to give a whopping 256 channels and used a chip that could turn on and off at specific points in the mains cycle (each cycle) to give dimming capabilities and the mighty C64 took over from its little brother.
Those were the days...

Yeah had a lot of fun in those days, things were much simpler and so was I.

Nope, but I was looking for something like that around 2007.
I wanted a simple display for the call center -- to indicate the health of the system I was working on at the time.
With essentially no user interface, there needed to be a way to indicate a problem to the supervisor.
Eventually, I wound up with a simple box with red, yellow, and green LEDs -- attached to the parallel port of the supervisor's PC.
Because I was writing the system for a taxi company, I would have preferred a "real" traffic light.

Soft and soothing music helps, like Memory Metal.
I have lived with several Zen masters - all of them were cats.
His last invention was an evil Lasagna. It didn't kill anyone, and it actually tasted pretty good.

I'm doing some code archeology on some old code written at the time when .NET was launched, and one of the really cool things was how you could write UserControls for the web and they would automatically be rendered based on the device. So for a webpage, they'd render as HTML. For a mobile device they'd be rendered as WML (Wireless Markup Language).
We put a ton of energy into writing a bunch of CodeProject code to support this back in the day, and every so often I stumble upon a small relic of this. It's like cleaning out a basement and opening an old cupboard only to find you still have a coal shootchute.
Edit: My abject apologies for writing "shoot" instead of "chute". Talk about being distracted by the news...

Alas, I remember coal chutes and hauling ashes (careful there).
If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.
