I find this program very interesting in that I have been told that it
is Turing Equivalent ie. anything that can be computed by any known
computing device can be computed by some life configuration.
I'm looking at a diagram where they have a circle with shading round
some 'very complicated mass of life cells too big and complicated to
show in detail here' with two parallel streams of gliders going into
it and one stream going out.
The streams represent binary codings (they've got pauses in them) for
Two numbers going in (encoded), the sum going out. Very nice.
My question is this? Its Turing equivalent OK but how on earth did
anyone discover the 'complicated mass' which doees this calculation
when two encoded streams of gliders representing the numbers to be
added in binary are fired into it? Apart from the mass of
complication which I can only guess at in the 'cloud' the gliders
would have to be very precisely fired into it.
