My most memorable VR experiences were a jellyfish/turtle scene and a closeup of a whale, among several games and apps I tried with my headset some years ago.
Games were fun enough, some good, some not. The visual, non-interactive experience gave me a true sense of awe, as if I were transposed into another reality briefly. Not a big fan of the whole "meta" idea, but executed and refined properly, we'll be in the matrix soon enough. Glad I won't be participating :)
