Do you enjoy cryptography as a pastime? If so, this is the contest for you. Adobe has reset their "San Jose Semaphore" art project with a brand new contest. There are 4 rotating discs with LEDs on top of one of the Adobe towers. Every 7.2 seconds they spin to a specific orientation representing a piece of the code. In the 2006 contest, each rotation was a letter from the 1966 novel: "The Crying of Lot 49." For 2012, I imagine this may be an even greater challenge. They also have an online version of what is being displayed on the tower over here.
The winner gets a one-year subscription to the Adobe Creative Cloud. However, after seeing what was involved in cracking the 2006 code, I think a lifetime subscription and a job offer at Adobe would be more appropriate.
