A "Exaggerate" mod or script?

Perhaps I'm drawing a blank here, but I can't think of anything out there available that works like this. What I'm interested in is a script or modifier that works the same as the "exaggerate" free-form brush in the Graphite Tools. What the brush does is make the features of a painted surface more pronounced by moving concave areas inward, and convex out. It's a useful brush for accentuating seams or bumps painted with the push/pull brush, or other techniques. However, I'm looking to accentuate the features of an entire object all at once, in the same manner that this brush does. I'm thinking of a modifier or script that would act like a two-way "push" modifier, by evaluating the topology for convex and concave changes in the topology, and accentuating them with a numerical value. Am I simplly forgetting about something already available naively, or as a script? If not, then would anyone be interested in writing something like this? I feel it would be useful for accentuating detail already modeled into a mesh, like wrinkles, folds, etc.
