This is a python script that converts edge selections and various component selections into locator or joint chains. You simply select your edge loops (or broken edge selections and in the Loopy Locator UI set your settings and click Create Locators or Joints. If you want to create a joint chain you must specify the general direction the chain should run (-x, +x, -y, +y, -z, +z) so that the script can order the edge loop selections properly when making the joint chain. To use the script simply run it in the Python script editor and then you can just type loopyGUI() to launch the interface. There's also an option to create a curve down the chain. The script has support for mirroring of chains as well as name prefixing.  Also if you have a joint selected with the component selection it will parent or parent constrain the new chain to that joint based on your choice to group the chain or not.  I'm thinking of adding in some splineIK options soon. Feedback is always welcome.
