Shards are kind 3330 and you'll find them on wss://cyberspace.nostr1.com. You can use https://sniffa-beta.vercel.app/ to query them

Yes, other avatars should appear in realtime but I need to do some testing on that 

 Can I post cyberspace notes to my own personal relay?  

 I'll be adding better relay controls in an update 🙏 

 Incredible! My own little slice of infinite cyberspace 🤗 

 (Its actually finite) 😉 

 I mean, if everyone can run their own relay with their own (non-consensus) version of the space, it's closer to infinite.  

 That's a good point sir
