I'm working on https://exeud.com. It's an open-source VR framework, including a Unity toolkit that includes character control and interaction, and a Web3 template that allows you to self-host your VR scene on the Internet Computer, which is a website-in-a-smart-contract.

I see it being useful for artists, indie devs and anyone else who want to fire up their immersive ideas and keep control of the content, code and costs of running it.
