There's no explanation of how to use it, or even a code snippet. And the documentation is down. So not very useful I'm afraid :(
If I'm coming to the website looking for that info I'll be happy to dig around a little bit to find it. If I'm coming to the website as a curious observer that information is not useful, it's wasting space that could be used demonstrating _why_ I'd want to install it.
Unsearchable name, Scheme-like syntax, no accessible documentation, no compelling examples ... not much chance of success. Still, the idea of a "language for making movies" is interesting.
