When i visited the Computer History Museum in MV a while ago there happened to be a live play session going on with the original hardware, with a bunch of excited people in this little room (the door had to be closed to create enough darkness to make that old screen visible).
I didn't get to play, but that was okay. Watching a bunch of (really polite) strangers huddled together, all excited about playing/watching this first graphical computer game was reward enough.
