Not sure this is the best topic for this, but was browsing online and saw that someone has developed "360 degree" onride cameras. They were tested on Colossus, The Swarm, Rita and RMT. As far as Im aware, they take a series of photos at a certain point of the ride and then stitch it together to create a 360 photo, with you as the main focal point of the photo.
Im not sure if this is something the park is looking into or if this is just some guy testing out some tech on the rides. Either way, it seems like Merlin have let this guy test out this fairly impressive tech on their rides.
