At first (and second) glance this image comes very close to looking like a display of Rene Descartes' illustrated cosmology (featuring his vortices ("tourbillons")).  The images are indeed similar--first, the mystery image, followed by one of the Cartesian tourbillons (from Principes de la Philosophie from 1644):
