i think having different locations can build horror. like the film about watch the vcr tape and the phone call. what was that called "the ring".
same as a roller coaster.
for porn i guess you can have a swirling table they lay on to get different angles, that and a camera on a movable pole you can get all kinds of weird shots.
all porn is is
- a choreographed set of movements that a animated gif could display
- repeat with different appearance
- repeat different animated choreographed set of movements
thats all there is to soft porn, hard porn etc.
