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

addition.

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.

I'm amazed.
