Wow... 10+ years this has been on the workshop. Fun find

Well done. :-)

EDIT: I've replaced the old outputs with doors, thanks to BeeMod.

MAJOR UPDATE: I've upgraded the chamber. Instead of a single demonstration of one type of XOR gate, it now gives a detailed guide on how to make a compact 1x1x1 gate.

yup you are right.. the size is not a big deal and your way is easier to understand

@Geneosis: Thank you :)

@shane716: Yeah, this isn't the most compact of designs, but that wasn't really the point. This is designed to be efficient in terms of number of entities, and to be simple to understand for beginners. And really, the size won't make much of a difference anyways.

I think this one is the best in terms of number of laser devices you need to make it ^^ Will add it to the Map Creator Tools collection ;)

Looks cool, but comparing with the https://developer.valvesoftware.com/wiki/Portal_2_Puzzle_Maker/Logic_Gates#XOR_gate
you XOR gate seems to need more space.
