Let's Build A Reactable - Surprisingly Affordable Multi-touch Awesomeness

Many types of touch and multi-touch surfaces are taking over our daily lives, but the reactable is arguably one of the coolest. If you're not familiar with the reactable, you should absolutely drop everything and head on over to http://www.reactable.com. The framework that powers the reactable is open-source and available at http://reactivision.sourceforge.net/

We have been working toward the goal of building a functioning reactable ourselves, and we finally have a product that is starting to approximate the real deal. We'd like to share what we've learned so that others might be able to jumpstart development or jump in on our project. Our reactable-like device will be present and (hopefully) functioning if anyone wants to check it out.
