I'm working on a human-like AI opponent for VR table tennis. It's something I really want myself, love playing table tennis in VR, but with online play you get the latency issues, people that have adopted a playing style which basically hacks the game physics or other aspects, or people who are just plain rude. Playing against the AI is much nicer, but it's not varied or realistic enough such that when you actually play against real people you are ill prepared.
At a very early prototyping phase, but having a ton of fun. https://x.com/artofpongfu
