This scene has 2 spheres that function as lenses. The first has an index of refraction >1 so it behaves as a normal convex lens and the other has an index of refraction of 0.75 which makes it behave more like a concave lens. There is also a surface functioning as a mirror above the scene and angle to show the colored shadows cast from the red, green, and blue lights.
