Iso geodesic distances curves wrapped in one solid mesh using cocoon from David Stasiuk "http://www.grasshopper3d.com/photo/curve-drivers-for-cocoon". Geodesic with multiples random points on gold rabbit and 2 points on blue rabbit.

Ahh ok, yes i understand, that paper is very interesting. The first diagram explains the distinction very clearly.

You are true it is not the exact wording. I must have said curves representing iso geodesic distances from points. 1 point on each ear of the blue rabbit. I have done an implementation of the exact "Fast Exact and Approximate Geodesics on Meshes"  . It could be used with on or more points. Many points could be used as an approximation of a curve.

The script is usable on "small" triangular meshes.

Nice effects, I really like the right one. Could you explain what makes it a geodesic curve, this is my ignorance, but my perception of geodesic curves are that they continue in a straight line. And if applied to the bunny would create a kind a criss-crossing pattern like pavilion below.
