We've been working on a new app and just opened up the process to beta testers. It's a real-time web presentation tool - allows a presenter to control display of images via URL. Really simple. Really effective.
And it's built with drupal.
The current pitch is for theme designers who need to take clients through work/mockup review. But in reality it's helpful anytime a) you are having a discussion supplemented with images and b) the person you're talking with isn't in the same room. Beta Testers get complete access to Black Tonic to use as they wish before the app is released publicly, which is still several months away. In return we need feedback. Lots of it. So if you have opinions, we're all ears.
