All I want for Christmas is a new release of Holler Gram

In March we launched Holler Gram, an app that turns your iPad into a glowing sign and simultaneously tweets into a predefined hashtag. It was perfect for conferences and we only did it as a bit of fun - which is why we are amazed that it's now been downloaded 45,000 times.
It's still being used by people all over the world and of the many fascinating uses people have found for it, the most humbling is from Australia where a group of teachers got in contact with us to say they'd been using the app to teach deaf children.
