Custom Loading Screen Samples

To get this effect I take the screenshots and loaded them into GIMP. First I applied the Oilify filter (Filter -> Artistic -> Oilify) using the default settings. The border was done by using the Fuzzy Border filter (Filter -> Decor -> Fuzzy Border) with a 32 pixel black border.

Oilify works well when there's significant color contrast or strong colors.

Here are some prefab areas from the Vault given this treatment.

And here are some of my own areas.
