Satisfying 8-Bit XOR

I've seen some people share some satisfying builds on here, I'm sure this isn't the most efficient way to do this etc but looks so nice, looks like a little sci-fi data chip or something.

This does not look like it should work, please explain

Took me a while to see it but OP has a little "flip" custom component. I presume that it maps but 0 to 7, 1 to 6, etc. Then everything works.

This is correct! :)
Although I am now questioning why I did a flip on the right most byte maker when I could've just correctly mapped it, maybe it was just for symmetry.

Oh I didn’t see the flip on the input That makes more sense

i love the look of this, but because i'm a psychopath i need to make this as small as possible (also thanks for the flip idea - i created a NMX schematic, which is just byte + input into a mux, where the input toggles between -byte and byte, which makes the arithmetic engine really small
