Chamber of Horrors is a nightmarish new demonstration of the immersive powers of Facebook's latest 360-degree video trickery.
Frozen in a single spot in the middle of a basement, you can scroll your view around a scene that feels horribly similar to the opening sequences of the original Saw flick. There's a body, an old computer monitor, and something moving about in there with you.
Stick on your headphones, dim the lights and blow this up full screen.
Good luck.
