While I was originally having just a bit of fun with the last shot, I have decided to spend a little more time on it and include it in the repo.
While I have a couple more fun things to add I have a couple shots to show what motivated me.
The first shot was just a static background layer. This last one uses the Decal layer in “bezel” scaling mode for the vintage monitors, and the Top Layer is used for the monitor LEDs, also in “bezel” scaling mode.
This is the Decal image.
As you can see it is only one monitor. The shader duplicates it and both screens can be moved in any direction or scaled in any way and the monitors will move and scale with them.
(The stray LED in the top left corner could be solved with a simple change to layer order.)
And here’s a night shot showing a single LED image being used on both monitors.
