From the outa-this-world-space-ui department:

Grok builder has made the spaces ui of my dreams. All you have to do is copy the url to the X space and you can listen anonymously by loading a new space, or you can sign in as your X handle and show up as you in the space. I used an ancient ampitheater and real NASA images of Mars for a backdrop. It needs optimized, and I haven't tested it as a spaker yet, but it does use the graphql (grok did it, I didn't ask it to) to get at the spaces api. Imagine this fully optimized. You might even get it to show up in a more realistic fashion in the hollowdeck, eh @Scobleizer ? If you didn't know, using the github connector, you can have grok push the code: github.com/toddfries/spacesf…
