A while ago I drew a comic about playing chess on a roller coaster. Various xkcd readers took up the challenge.
Pictured above: Andrew Burke, Chris Ranker, Ryan DowlingSoka, and Chance Brown.
To see more pictures of chess on rides, go to xkcd.com/chesscoaster. If you think you can do better, go for it, and send the pictures to firstname.lastname@example.org. But remember, I am not advocating doing anything dangerous unless it’s really cool.
