PanoMoments are a new short-form VR format. You can think of them as the GIF or living photo of VR. Get started by uploading a 5-10 second 360 Video clip taken from a fixed location, tweak the rotation, and you're done!
Playback is possible using pretty much any web browser, though Chrome is recommended. For higher performance playback, check out the native app running at 60fps. And for total immersion, use Google Daydream or Gear VR.
