The hats go back in the box in a few days, but as they say, "The Internet is Forever."
In previous years, people have made backups of the hats in their original SVG files (not just screencaps). Has anyone done this for this years hats?
I've done the hard work again this year and created a GitHub repository with every known Winter Bash 2017 hat.
Each hat is available in their original SVG format, and a PNG convert. The common ones were extracted from the CSS stylesheet data URI's, and the secret hats were downloaded from their secret URL's.
Incidentally, no need to save separate outline files this year, as they were created with CSS filters.
.wb-hatimg-stroke {
opacity: 1;
filter: contrast(0%) sepia(100%) hue-rotate(202deg) saturate(80%) drop-shadow(0px 0 1px #fff) drop-shadow(0px 0 0 #fff) drop-shadow(0px 0 0 #fff);
}
NOTE: Keep in mind that these hats technically belong Stack Exchange, and their license is currently unknown, though it has been permissive in previous years.
