From what I remember, Sandstorm is a content management system which relies on installing little "apps" which run in it (which are typically pre-existing programs made by other people, but really stripped down, so worse), and these are hardly ever updated.
There, you have it, Sandstorm. A novelty project.
When the developer describes it, he makes it sound like some futuristic thing, but it is really just bad.
Surprising that someone would actually use it.
