Welcome to the Machine is a real experience. The throbbing of the machine, to describe even that part alone is a challenge because lots of systems can do the throb but it wasn't until the DBA the character of the vibrations is felt as this immense, uh, machine. The door at the end, the airlock, you really feel it. Like those of a certain age will remember the VW Beetle, the way you had to almost slam the door because it was so well sealed, and the pressure wave when you did that. Kind of pressure made some people crack the window to avoid. Years later carmakers figured out how to vent that to have the seal without the pressure slam but for a while there we had the pressure slam.
Well it feels exactly like that only instead of being in a tiny little VW it feels like you're in this much bigger space. Which then you feel the door slide open and as the door opens wider so does the space in front of you and its oh my freaking God this thing is HUGE! And there's all these people and you can hear every individual one of them spread out there in 3D and its like how the hell did they even do this??!
Who knows. But there may have been purple micro dot involved.
