Seeing this for the first time, I have two ideas for a torture device:
1. We will strap the person in a chair with mechanical ai hand. There will be a tv screen consisting of Youtube shorts that manipulates the algorithm of only showing brainrots. Their head is fixed to the screen, with headphones attached to their ears at all times. After every 7 shorts, the hands will feed them 2 brazilian nuts, and you should know how dangerous it is to eat them a lot.
2. It requires making the torture piece actually part of the art museum. Place the person on top of a strong glass ceiling on the rooftop lying down, just visible enough for people to look up and see. Then have a human-sized hydraulic press and slightly press them down, not too hard but just enough for them to not escape. Now have a timer to say 7 days to the machine for it to pressed them down slowly and painfully until the timer reaches to when they are squished to death. People will probably think it's all part of the show and they're not wrong.
I think the second one will win.
