Each block is a 1-bit adder (right output is sum, left output is carry)
The whole thing will be a 4-bit adder adding the numbers 5 and 4 giving the
result 9.

Hey! That's a model of the new AMD 64 right? Can't wait to see the final
image! ;)

It's a better mousetrap!  Better widen your front gate...

A logic circut showing different results from different input?

The halves of the lower AND in each adder seem to be coloured wrongly.

Not if you use my logic :)

Thanks people.

Yes, it's a binary adder.

I repeat: it is NOT finished yet - there are still some connections missing
from the picture (but influencing the logic anyway). That's why it doesn't
make a lotta sense yet.

This thing involves *miles* of code... I've manually placed tonnes of
cylinders and spheres (for the joints), not to mention the gates themselves.
I think I really need to rethink the way I'm coding this or I'll be here
till Christmas!

But anyway, at least people recognise it as a set of logic gates. That's
something!

Thanks.
Andrew.

Congratulations - we have a winner! :-)

PS. Couldn't be bothered with 64-bit arithmatic...

My solution would have been to make the 1 bit adder as a macro, then use the
input states to determine the color map.  This gives you the ability to actually
animate the process of addition and carry in realtime, not worry about the
colors yourself, and get rid of most of the "wiring".
    I can see some macros coming on- stop me, somebody!

Individual gates are already macros. (Which is why the logic states
propogate despite the fact that I haven't drawn the wires yet ;-) I've
re-coded this scene a zillion times in the last week, and I just can't find
an uncomplicated way of doing it :'-(

I guess I'm just a sub-standard coder.
