Circle Cross Hyperbolic Rhombus:
A simple construct of a circle and hyperbolic rhombus with orbits slightly off center respectively used as "agitators" of the direct feedback formed by sending the shapes into a framebuffer. A simple audio oscillatorfiltermodulator combination is used to modulate the shapes and so the feedback.
This example as well as Circle X Circle is reminiscent of a Poincaré disk used when making sketches in hyperbolic geometry.
These examples are targeted at the beginning college student, as often they are not exposed to the ideas of nonEuclidean geometries until late in their undergraduate studies if at all.
