The Museum of Other Realities (MOR) is an innovative social VR platform dedicated to showcasing the best in virtual reality art. Previously. you had to buy the program, but yesterday they announced that MOR is now free to visit. (I wrote about the platform previously on my blog here and here.)
This is definitely a do-not-miss social VR experience! Be sure to visit the tutorial room first to learn how to properly navigate within the museum. Even better, you can enjoy and experience the artworks with your friends—all for free! It will take you hours to go through all the galleries and exhibits.
The Museum of Other Realities requires PCVR (i.e. a higher-end VR headset attached to a PC, such as the Oculus Rift, HTC Vive, or Valve Index), and it is available to download via VIVEPORT, Steam, and the Oculus Store.
