Kickstarter: Tembo Trunks

I'm doing some research before I start my own Kickstarter project and I came across the Tembo Trunks. Such a simple and brilliant solution to a problem that I encounter every time I travel with my iPad. How do I get the audio loud enough to watch a movie (or listen to music) with someone else without lugging speakers around? The answer is Tembo Trunks. I immediately backed the project to get myself a set.
