And the bus is full of people.
It's actually the same person. It's just one skeleton.
And back in the '60s,
they used to teach student radiographers
to take X-rays, thankfully not on you and I,
but on dead people.
So, I've still got access to one of these dead people
called Frieda; she's falling apart, I'm afraid,
because she's very old and fragile.
But everyone on that bus is Frieda.
And the bus is taken with a cargo-scanning X-ray,
which is the sort of machine you have on borders,
which checks for contraband and drugs and bombs and things.
Fairly obvious what that is.
So, using large-scale objects
does sort of create drama
because you just don't see X-rays of big things that often.
Technology is moving ahead,
and these large cargo scanner X-rays
that work with the digital system are getting better and better and better.
Again though, to make it come alive
