Firewatch is extremely beautiful, thanks to hand drawn art by artist Olly Moss, and clearly developer Campo Santo thought so to, because there is a feature in the PC version of the game, that let's you physically develop the images you take with the game's snap camera.
TechnoBuffalo saw a little link in the main menu after they finished the game, and that link took through to a website, which offered to develop/print the taken images.
The results can be seen below, and they'd look good on any wall.
