You’ve always been able to add paintings and other decorations to your ramshackle, rusty tin huts and crappy plywood structures in the wasteland of Fallout 4, but now, thanks to one enterprising modder, you can add true happiness to your post-apocalyptic settlements.

Modder Johannes Nyman has given PC Fallout 4 players the ability to replace four in-game paintings with landscapes painted by famous PBS personality Bob Ross. The paintings each come in two flavors: the spotless, pristine versions from before the atomic bombs fell to destroy the world of Fallout, and the grimy, post-war versions, because apparently no one can clean anything 200 years after the end of the world.

Still, even dirty versions of Bob Ross’ happy little trees and clouds should be enough to lighten the spirits of the modern wastelander. The mod is available for download here.
