This Christmas we are donating money to Crisis, the national charity for single homeless people. We're making our donation process a bit more interesting through an innovative little social media project we’ve created as one of our internal experiments at Curve Agency. We call it the Christmas Curvecake and you can “tweet to eat” it on our site, or just by including #CurveCake in a tweet.

Of course, you’re always welcome to simply donate your own hard-earned cash directly by using this JustGiving page or however you want!
