PCB RE aid idea. A fluid that will temporarily change colour when subjected to a charge. This would allow you to follow a node around a PCB by dunking it and charging the node.

@RueNahcMohr@infosec.exchange With PET flexible PCBs, one can make see-through sensor arrays to build up E-field "viewing film".
Should be enough for visual inspection in proximity? One (dual) WLCSP FET and 0102 resistor per pixel?
