This is an MDM-login theme.It is mostly made out of zukitwo elements, but it is rather neutral so works with anything.
- Extract and move the 2 folders into usr/share/mdm/html-themes.
- Select the theme from system settings-->login window.
I made 2 versions.
-One uses a pattern.
-The other uses a wallpaper which you can change.(In case your wall ends in ".png" or else then open the "theme.css" file and search for "bg.jpg" and rename to your liking!)
The second version uses a css filter to dim down the wallpaper.Search for "-webkit-filter: brightness" in the "theme.css" file.
I encourage you to try out various cool filters.Like blur.
I isolated all the selectors into one "theme.css" file so you can style the whole thing with just that one css file!
