HarvardX invites creative coders everywhere to a learning technology challenge.

The mission is to create an interactive visualization of the binomial distribution suitable for students who are learning the topic of probability.

Possible approaches include interactive line or bar graphs, coin-flip or dice-roll simulations, combinations of these, or something completely different.

Winners will see their work appear in a HarvardX open online course.

Submissions are due November 1, best entries decided by November 10, winners announced November 30, 2014.
