I remember actually working on some of the puzzles that were posted by ITA in the Boston MBTA subway. I didn't submit them (since I wasn't interested in working at ITA) but they introduced me to interesting problems. For example, there was a problem related to generating rebusses* whose solution contributed to the solution to another problem I was working on. *http://en.wikipedia.org/wiki/Rebus http://en.wikipedia.org/wiki/Rebus
