I've heard of a lot of weird ways of storing bits, but that's by far the strangest.
It's like embedding a mechanical telephone in the box, and having it talk to itself with it.
There seems to be roughly 10m of wire there. To space 400 bits out along that wire would leave 2.5cm between bits, which at the speed of sound in steel (~5800m/s, depending on the type) yields around 4 microseconds between bits. That's really incredible.
