Blender internal dispersion and caustics effects. If you currently have caustics turned off in Cycles, this will make nothing faster or less noisy. Blender users have recommended using Filter Glossy to blur caustics that can be found in a scene with a lot of reflective materials that would also cause noise, or turning off caustics altogether in the Render Properties tab. Shading and materials are essential for every Blender artist. From what I could tell in the initial logs, the filter glossy option inflates some sort of sampling hitbox so as to make the path easier to find and faster to converge (while adding a softening effect to any caustics formed). Nion has come out with a great tutorial this week on how to create dispersion and caustic effects in Blender. Edit 2: It also can help to set the clamping of the direct and indirect light. Hope you enjoy it! It just defines how that particular wavelength interacts with the surface. Adding realism to the keys with a bump texture. In optics, a caustic or caustic network is the envelope of light rays reflected or refracted by a curved surface or object, or the projection of that envelope of rays on another surface. Offering both biased and unbiased rendering, Appleseed has a greater capacity for providing detailed caustics than Blender’s internal engines and the power to deliver beautiful results. Also If you create some more abstract motion graphics this small light Edge can enhance the final result. The glass shader tends to cause noise due to caustics. And of course, as motionblur says it will put Blender on a nice stand with comercial apps if the new UI is nicer looking and easier to "learn" cause we all know it's absolutely awesome to work with once you know.
