A real 3D scene in WebGL2: a glass prism (beveled mesh with fresnel and refraction) on a reflective vinyl floor. A light orb follows your cursor and fires a volumetric beam; the spectrum fans out by Snell's law, one ray per color, and lands on the wall and floor with its caustic. The camera parallaxes with the cursor.
