This feels just a few steps removed from bringing the technology from the 1990 film "Total Recall" to life. Clients are able to purchase completely custom memories, choosing the exact characters that will appear in their "vacations", their ages, and appearances.
I'm also kind of reminded of A Scanner Darkly. That would be another interesting movie to reconstruct this way.
I'm also reminded of those posters in the mall, where from a distance, it's an actor's face. But when you walk up close, it's actually made of hundreds of stills from their films.
