Cellular Automaton, Part I

I have wrote a Wireworld CA program in Java and have realized how the OR-gate & XOR-gate works, but I'm still having problems with realizing the AND-gate. Anybody have some experience with this cellular automaton?


//The OR-gate:

0 0 0 0 0 0 0 0
0 3 3 3 0 0 0 0
0 0 0 0 3 0 0 0
0 0 0 3 3 3 3 0
0 0 0 0 3 0 0 0
0 2 1 3 0 0 0 0
0 0 0 0 0 0 0 0

//The XOR-gate:

0 0 0 0 0 0 0 0 0 0
0 2 1 3 0 0 0 0 0 0
0 0 0 0 3 0 0 0 0 0
0 0 0 3 3 3 3 0 0 0
0 0 0 3 0 0 3 3 3 0
0 0 0 3 3 3 3 0 0 0
0 0 0 0 3 0 0 0 0 0
0 2 1 3 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0

No, no.
Colourised "TEXT" //is an 'art form.

>>18
Colourised "TEXT" is //an art 'form.

>>19
Fuck.
Colourised "TEXT" is //an art 'form.
I knew I was forgetting something.
