I love POV content but it can become a bit samey. the voyeur stuff can be really be a nice change.
I've often thought about how endless the possibilities are with combining 3D and voyeur porn.
Imagine for a moment that we live in the future and high resolution 3D camera rigs are dirt cheap.
A porn set could be fitted with hundreds of cameras, some on the floor, some on the roof, all around the walls etc. Multiple different heights etc, but All pointed towards the action.
Theoretically you could shoot a scene and with enough cameras that the voyeur could get have a full seamless 360 view of the action, and just watch from whatever camera has the perspective he pleases.
It would give the option to watch the same scene repeatedly from multiple different perspectives.
