This demo was first displayed at a United Adoration meeting near Sewickley, PA.
Created by Matthew L. Hornbostel, likely to see a release as a small free program in Windows .exe and Android .apk format. Tour will have 3d rendered scenes to freely look around in, about a dozen 360-degree views of various points of note in and around Jerusalem at the time of Christ.

While it will be largely 'on rails' and you won't be able to walk freely, there will be an intriguing variation intended for use with Google Cardboard. In that one, every scene will be in stereo for basic VR use.
This will allow a certain immersion not possible without the 3d effect.  

Though this has been on the backburner for a while, I'm optimistic it'll be available here before the end of 2024.
