Wire crossing with no crossing wires

[killing_you_guy_]

Sort of, but now I'm having trouble squeezing it into a reasonable space. I'm lining up the xors and sending the other lines around the sides. It works like the. Algorithm for searching variables without a third variable, where you do a=a XOR b; b=b XOR a; a=a XOR b;. If I can make more improvements, I may make a flat alu or even computer.
