Thought the forums were a bit bland, so I made a userstyle for it. It’s a transparent theme for use with a background image of your choosing.
I made this for myself, with a specific background in mind, so it will probably not look great with just any image, but I’m sure you can find one which looks good if you’re willing to compromise. The background image URL is located at the top of the style so it’s easy to change, though there is also an option to set it permanently. Currently there are a few other options available as well, though they might not work exactly as intended; as I am not using them myself they have not been extensively tested.
If you have any thoughts or complaints feel free to voice them.
The theme can be installed through userstyles.org
