I used blender, an open source 3d modeling program to trace a batman logo, turn it into mesh and mold it into a paperclip format.
Here is my .blend file: https://dl.dropboxusercontent.com/u/18723152/batman.blend
This is what the final results look like (more images on the last page)
Step 1: Tracing
I started by getting a clear image of the batman log from: http://www.vectortemplates.com/raster-batman.php
I imported the picture as a background image in blender ( You can find such option by pressing n on the window)
Press Shift+A, under curves, go to nurbs curb and in edit mode (press tab to switch modes), move around the vertices to trace over the curves.
Press alt+c to convert curves into mesh, join all the curves, and in edit mode (tab), press f to connect the end points
after tracing half of the image, duplicate (shift+d) and rotate (r - 90 degrees) and connect both traces
on the top(head), you will have to recreate the curve so you can fill in the mesh
press alt+f to beautify fill the mesh and then extrude it
