That's pretty cool. I had seen this a while back (haven't been looking at Pinside much), but didn't see exactly how it worked until now. I've used those little screw terminal type boards for non-pinball stuff before, but never thought about it being a clean way to route power around the game and then just split it out where the connection is needed (also simplifies mods being easily disconnected at the mod instead of fishing wires through when you have to do stuff like remove a PF).
Pity I don't have a modern game anymore to use it with, so this isn't an entry, but I like it.
