Side note, the Connection Machine is pretty much the coolest looking computer ever: https://www.computerhistory.org/revolution/story/73 It looks exactly to me what a powerful and slightly scary computer from an 80's movie looks like.
Also, the T-shirts! [2]

I've got docubyte's poster of the PDP-7 and it's great.

At the computer museum in Alpharetta Georgia, none of the computers are on but the connection machine panel is on.
It seems like the reason it's on like that is because it used to belong to the NSA so they took all the insides out and destroyed them when the machine was donated. The blinkenlights are driven by Raspberry Pis or something similar.
