The XOR Gate, easily visualized

Description
The easiest way I could think of to demonstrate how an XOR logic gate works in Portal 2 using lasers. This logic gate was made of three laser emitters and three laser receivers.

The two buttons are the binary input and the fizzler field is the output. The output is only on when a single input is on. The logic gate essentially acts like three light switches all wired together.

The traces are all clearly drawn on the ground so you can see the connections happen as they're made. None of the traces cross over each other in this pattern, ensuring it's all easy to see and understand.

Bungle I hope you are not mad at me now. The reason why I posted here and over at your perpetual laser power map is just to show you we have common interests and I'd like to request your friendship - if I could find the button.

Hmmm, forgot this one ^^ So it's the second simplest XOR gate I saw ^^

I was able to create an even easier one with just two NOR gates. Maybe you're interested:

Probably the most simple and well presented XOR gate I saw ^^
