I wasn't sure the guys knew about the Sphere in Vegas. We attended a custom-created film highlighting the technology called, "Postcards from Earth". I did a quick YouTube search and included this video about the building because it was fairly concise and mentioned about the concept of beamforming and how it is accomplished at the Sphere. We use a group messaging chat.
What made it more timely is that Jay happened to see videos about the opening of a classic movie reformatted for the Sphere. He saw video that guests had filmed when additional features of wind and debris started flying around during the hurricane sequences. As one of the group members is interested in musical scoring of orchestras I relayed the movie through another YouTube clip.
I saw some other videos about the processes and how AI was extensively used in reformatting the video for the nearly-four-acre screen. However, in the group chat I just included the following webpage that has video of the exoskeleton of the building. It shines both day and night and is tremendously impressive when things get dark. The 'advertising' is varied and so I'd suggest returning to this page often!
