Hell yeah! Manhunt 2 reference!
SPOILERS
Also, I loved the story. I did expect there to be a scene where we would see the students or at least one get Vitruvianed on the machine. But seeing it, it made me begin to think to myself. Never tried coming up with a torture device but why not try? Before I got to the end of the story, I actually came up with a similar idea to the Vitruvian, my idea was that they'd be laying on a circular machine like that, their limbs would extended and it would replicate the 'movement' of the Vitruvian to an overextending degree. I didn't think it was enough pain, so instead of the arms movinag above their head, it would twist and go backwards, there would be a bar that would be in the way of their elbow breaking it, same for the knees as the machine moved, after those limbs were broken, the bars would automatically go down out of the way to allow movement again, then would force them into splits for their legs and arms bent behind their head. And I noticed practically all pain seemed to be focused on the arms, I wanted to take the pain to the body. The chest, just under the sternum or in it, is a place where most the nerves in the body like to gather before going back up in the brain, so a hydrolic would press down and break their sternum to squeeze the pain from that. This would both maintain most blood loss to without lethality or crushing their heart. You get arms, legs, and all the joints in them, in the reverse human plus Vitruvian kind of way plus the bonuse of breaking that juicy sternum without death. But for the kill switch, an ultimate display of gore, plus the ability for the feeling of remaining pain for the victim would be the circular machine would then rip the victim from its lower torso allowing for all those intestines to spill out and ultimately, death.
Tell me if you like it.
