I absolutely love these and i would love to have them on my desktop. You say in the description that they can be used as a screensaver so maybe you know how to? Other than just letting Factorio idle in the background.

Glad to hear youre enjoying it :)

When I say screensaver I simply mean running the game with the main menu open. You can set the cycle time to like 10 minutes, and then slowly have the factories running.

I don't much about Wallpaper Engine, but I doubt that it will be easy to port this mod to that. The engine will have run Factorio in the background, which can still be intense. The one simulation is still literally a 1kspm base running in the background :)
