By inspecting the page and checking the console message, I see a cross-origin request blocked with a link[developer.mozilla.org] to read up more about it. I can't run the index.html directly. I have to access it through a web server instead (meaning I need to use http:// instead of file://). The link describes how to do this. I used Node.js to setup an http server for the local project.

Hey there, Thanks for your interest in the wallpaper. As you have noticed, it has originally been created without npm or any package manager or bundler. Hence, you can't simply install jquery on it ^^
Also, jquery should already get included from the "js" folder. So I'm not really sure what your problem is or was.
Let me know if you still need help :)
Regards

Thanks for the response. Yeah I don't know how it works at all. I just followed the link in that error message when I opened index.html. I'd like to run your latest one day. I got to learn a lot about Javascript by playing with your code :).

Alright :)
First of all, it would be good to know exactly what you are trying to do.
Why do you want to run the "old" 2.3 version?
Do you want to use it as a wallpaper or just as a visualiser?

The easiest way is to use the "Wallpaper Engine" on Steam.
It will download the wallpaper when you subscribe to it via the Steam Workshop, so you can use it completely offline or "locally".
There is also a free open source alternative called "Lively Wallpaper" which works in a similar way, but does NOT use the Steam Workshop version and requires some modifications:
https://github.com/rocksdanister/lively

You can find the 2.4. "Lively" Wallpaper version for download in the github releases section:
https://github.com/hexxone/audiorbits/releases
If you need the 2.3. "Lively" wallpaper version, you can find it as a forked repository here:
https://github.com/rocksdanister/audiorbits

Unfortunately, if you do not want to use it as a wallpaper, you will need to run a small web server or configure your browser with special arguments to allow it, but explaining this would go beyond the scope of this wallpaper. In this case you will have to do your own research :)

Hope this helps, best regards.
