Sure thing, I don't have an example with say, half-blown, half-not, but
here's the exact same set of traces as above from another copy of that
board:

I think at worse a frensle lense would be just fine for making the whole
thing visible. Heck, put a magnifying glass on a string next to the
peice when it's on display.

Backlighting could be interesting... Make it so the peice's back is
fully transparent, so you could hang it by a window. I think even
standard PCB material is translucent enough to achieve that. Makes
finding a spot to put the batteries harder though.
