Meta: Someone please correct me. The outside of the Sphere is pretty damned awesome, with its interactive elements and novelty. I'd visit Vegas just to watch it, not that they'd make any money off me for that. The inside looks like an IMAX theater combined with a few planetarium features (lazors?). And, well, I have a really nice IMAX theater only an hour away from me. Why would I pay a premium to see the one in Vega…
The screen to some extent will be dependent on content produced for it (some very cool optical illusions are possible with a spherical screen), but I hope the audio tech will make its way into most large music venues over the next few decades—it’s just that good.
