This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Looks like the coating above the traces didn't quite stand up to the heat over the years.
But it looks nice, maybe we can make PCB art with that.
That might be it. I was thinking it could the a spike in voltage that shorted the traces. But nothing else got damaged in the house, so it is less likely.
