I randomly stumbled across this gist by tenderlove https://gist.github.com/tenderlove/4576780 that displays references as a tree view using d3.js. I think that this gist in particular is pointing out a bug in that the "references" for Fixnums (also Symbols) in an array aren't returned by ObjectSpace.find_references.
