Spherical projection, both on a small sphere and under a planetarium dome, is a great tool to entertain with astronomy and space. But also to teach science, geology, geography, history, math, art…. and who knows what else.
There are many existing commercial or open source systems based on this simple but revolutionary idea.
Untill now, these products usually required high budgets, couldnt be transported easily and sometimes, were difficult to use for non-trained users. Whatsmore, usually the final users didn’t play any part in the building and setting phases, nor in the production of educational contents. And as you will learn, this is part of the added value and of the fun.
For these reasons, we decided to develop a portable and cheap spherical projector that can easily be built and used with clear and customizable educational content by anyone, not just experts.
