7 Undeciphered Writing Systems: Scholars at Oxford University recently asked for help from the public in deciphering an ancient writing system.

One reason the tablets have been so hard to decode is that they are full of mistakes, making it hard to find patterns. They hope that crowdsourcing will uncover some leads. In the meantime, here are 7 other scripts you might try your hand at deciphering.
