When making electronic circuits it is very difficult to get a lot of wires in a small space, so I suggest making a few elements.
ELE1 ELE2 ELE3 ELE4
Okay they are basically metal, but they can only accept electricity from the P metal, battery and their own kind of metal. This would mean in a space of 4 pixels (2x2) you can have 4 wires running by alternating 1 and 2 on the top layer and 3 and 4 on the second.
For people who got lost with what I meant basically the wires can only transmit current to them selves, LCD and P metal.
lol, I just finished a insulator element which blocks electricity between elements... meaning in a three by 3, using alternating NTCT and PTCT alternating and METL in a wire with a insulater layer you can have 5bits per 4x4 area
