+   description: "The TAs creating the endterm exam have suffered in the past from leaked drafts.
+To protect themselves against further leaks they invented the *mega obfuscated secure advanced information communication* (mosaic) system.
+The mosaic system encodes emails as QR-Codes and then applies the ultra secure protection algorithm.
+We found a QR-Code that was not disposed properly in a waste bin.
+Can you decipher the email?
+Hint: 
+1. The mosaic algorithm adds decoy fake data to the QR-Code. It is mega secure after all!
+2. Save yourself from the headache of searching for QR-Code libraries: https://github.com/NaturalHistoryMuseum/pyzbar"
