Had a blast testing this in anticipation of Quest 3, you can find all sorts of characters on Vroidhub and its all connected to the app so the effort is very minimal to get those characters in. You can play games with them, get them to dance, or setup chat gpt in it with google voices and chat with a virtual character in your room. I cant wait to see if this gets further updates after Quest 3 but its already a great example of what Mixed Reality can do.
