There are new Steam animated background introduced in this summers sale event.
An example can be seen here: https://steamcommunity.com/id/CorruptComputer/
The jpg for it doesn’t seem to work on SteamHunters, since I assume its expecting it to be part of a game, which it is not. However I think it would be really cool to be able to use the animated versions on SteamHunters as a background on our profiles.
Here is the HTML from Steam with the various formats it is available in, for me when I right-clicked it on the webpage it seemed to give me the webm version, but there is also an mp4 available.
