At every FUDCon event, people create name badges as part of our collateral.

For FUDCon:Tempe 2011, ianweller created a Python script that makes beautiful badges from a CSV file. These badges are designed for 3in x 4in inserts, and use the FUDCon Tempe logo. You can edit the input SVG to substitute a different location. You need all three of these files to make badges, although you'll want to edit the CSV appropriately.
