A Seasonal App That Puts Christmas in Your Dropbox

Engineers at Dropbox, inspired by a novelty Twitter account, built the website "Is it Christmas?" It answers that pressing question by adding a new photo to a user's Dropbox every day. The app is more than a festive gimmick: it shows how a service can periodically update a user's Dropbox via the copy_ref API method.

How it works

The app, written in Python, relies on a small set of Core API methods. State is kept in Redis, which stores each user's access tokens, time zone, and the last photo added to their Dropbox. A cron job uses that data to drop a fresh image into everyone's account at local midnight, daily.
