There are assistant tools for reversing die shots, by the way. Semi-automatic, not sure if we've gotten to the point of fully automatic yet.
Do we have tools for exposing specific layers instead of 2D images? It would, perhaps, be interesting to go with diagonal slices as we grind the chip and, aided by exaggerated vertical features, capture the full depth on a single pass.
