What collaborations has Ken Walker engaged in within the virtual reality space?

In the VR space, a couple things are public so far:

• A paid collaboration with Sandbox VR, sharing “a little VR with a lot of us ❤️👾,” highlighting their in-person, full-body virtual reality experience.
• Ongoing work inside Meta’s Horizon Worlds, where a custom world is being built as a space to talk about mental health, inner peace, self-love, and growth in a more comfortable, less face-to-face setting.

Is there a specific type of VR collab you’re most curious about—gaming, mental health, or community hangouts?
