There is a 4-page article describing Oskar van Deventer's Over The Top 17x17x17 Cube Puzzle in the September 2011 issue of Games Magazine. It is on the newsstands right now - for the next 2 weeks or so.
Games Magazine can be found at Barnes and Noble, Borders, Target and other stores that carry a lot of magazine titles.
Because I am the Mechanical Puzzle Correspondent for Games Magazine, I was assigned the task of covering this story.
Games Magazine has a minimal presence on the web: they don't post articles or puzzles and they often don't update it in a timely manner. Buy your copy today! Bring it to the next International Puzzle Party or New York Puzzle Party Symposium and get Oskar and myself to autograph it.
