aesthetics of ‘gas chambers’.
I know what you meant, but the visuall aesthetic of a gas chamber is fucked...
I got tear gassed in one in bootcamp, and the thing that sticks out the most is how ominous and sanitized a room like that is.
Obviously not the same thing, but everybody had a "holy fuck" moment when we were walking in and being ordered into ranks and everything.
There was a lot of very surreal moments like that.
