FSF Hackathon and LibreVR project

I will still continue working on a VR headset that will run Trisquel GNU/Linux. That is a long time goal for me, with Respects Your Freedom Certification[1] in mind. Once I ran libsurvive in a Trisquel chroot on a smartphone running LineageOS. That was fun. For the FSF40 Hackathon[2] I plan to package both libsurvive and Overte in GNU Guix.

So my question: is anyone in this Trisquel forum using GNU Guix or going to participate in the FSF40 hackathon? One week after the Hackathon I plan to do a livestream on [3]
where I will also talk about Trisquel's Virtual Reality projects, and why those Godot 3 games do not currently run on my VR setup (Talos II + Valve Index).
