I know it's a bit down-to-the-wire, but I (finally! ;)) finished a new
revision of the beta wallpaper. It's up on the wiki now here:
I replaced the light spots/lens flare with a light streak/aurora effect.
I don't have the source file uploaded just yet - it's huge! - but I'm
working on it and I'll post a link on the wiki ASAP.
See what you think!
