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

NOR isn't a word.
NAND however is. Unless we define word as less or more than 32 bits.
