For their 20th anniversary, the Graph Drawing Symposium has issued a computer game development contest with relevance to graph drawing. All attendees of the Graph Drawing Symposium in Redmond, Washington, have been invited to play all the submitted games and to score them. The iPad game CrossingX, developed by Tobias Brinkjost for his Diploma thesis, convinced the audience and did get the first prize of the contest.
