Working with projectors

During a workshop in the Crawford College of Design, different ways of projections where tested for the installation, such as projecting on tissue and overlaying several projected images.
The major goal was, to see the result of a processing sketch (witch a black background) being projected onto a projection of Stellarium. Here are the results:

As for now, a mainly black projection does not seem to affect a projection of Stellarium much. So projecting different ways of visuals for hydrogen onto the projection of Stellarium does not appear to become a problem, as long as the background of the visuals is black.
