I first created a folder for wallpapers and inside placed two images "Second wallpaper" and "Second Wallpaper alternate version". They can be found in this website:

After that I placed both images as my wallpaper and set them to change every ten seconds. Since both wallpapers are the same and the only difference that the alternate version has glowing parts every time that it changes it gives the impression of it getting activated and deactivated every few seconds which is pretty awesome and creepy in a cool way.

The next thing that I did was downloading the font "Heretica Inquisitor" from this website:

It seems that the site is down now... I'll see if I can upload the font on my own at some point.

I used three diferent rainmeters to achieve that effects. Those are:

I got most of the stuff from the first rainmeter and changed its parameters to turn the characters red, some of the things like the recycling icon are images and those had to be changed in photoshop. It was easily done by using the "substitute color" tool.

From the second fallout rainmeter I only got the music player.

Finally I placed the Monstercat visualizer and changed the number of bars so it fitted better in the gap.

And thats it!

This is how I imagine that some Adeptus Mechanicus cogitator desktops of the 41th Millenium looks like.This was done with Rainmeter and some wallpapers that I created on my own:Walkthrought:
