I'm the maker of Singularity Stream Kit, a downloadable tool for people who want their Starting Soon, BRB and Ending screens to share a cosmic look.
Add your channel name, message, palette and logo in the local editor, then export a self-contained HTML scene for an OBS Browser Source. The kit includes three galaxy formations, an optional countdown and three quality settings. It's US$29 once, with commercial use on the channels you own under the included license.
I built it with substantial Codex assistance. The scenes are silent and opaque; they do not include chat alerts or automatic scene switching.
The project page has the downloadable kit, setup details and interactive preview. I'd welcome feedback on which customization or setup step needs a clearer explanation.
