There was an art piece (at Burning Man, where else haha) that replicated this to some degree - simply a chill couch/bed thing that'd comfortably fit about five, with headset microphones and a projector, which'd visualize the sound.
And... however they put it together, it was magic. You really did feel like you were singing shapes into existence with your friends.
Oh jeez. I think that was 2013, and I think outer playa, but not deep playa - past the temple where things get calmer and more isolated, but not way the fuck out there.
I have no idea of the names involved :/ I might be able to recover it, as I think it was by some friends of friends.
I love the electric lazy, but that's not it :) The lazy is passive (you experience it while it happens), this was interactive.
PS - Did you know you can get a portable version? It's just the goggles, plus the sound/visual combos. (Or, at least, you used to be able to, haven't checked in years).
