For Twilio's most recent developer contest, I decided to build an app to allow you to use their new in-browser Client API to record an audio message for your friends' birthdays.<p>There's plenty of room for improvement, like the ability to schedule birthday greetings to be delivered to friends on their birthdays in the future, which I might get to someday.<p>I'm also aware of the implications of people not allowing apps to see their birthday (even with the 'friends_birthday' permission granted to the user), so not everyone will necessarily show up in the list in the app. Sadly, there's not a workaround that I'm aware of.<p>Anyway, let me know what you think! This is the first hack project I've posted to HN. :)
