As I pointed out to the OP on Mastodon, I very much believe that it was a reference to Lawrence Livermore Laboratory, where they filmed a big door, and the original laser sequence from the first TRON movie.
you'd first have to program it to take the picture, and look back at the photographer's eye to get the reflection of the screen with the IP address on!
Michael Sheen is apparently such a fan of TRON, that he might have been lucky to not negotiated himself down to a $0 pay packet - just in case someone else might have gotten the role :D
LLL also made an in-house video when they were filming the original movie - https://www.spyculture.com/dept-energy-invent-making-video/
