Please Add A Mica Flecks Layer/Filter

[msjphotography]

Gang, I would love to see a layer/filter that allows the user to add tiny flecks of mica to materials, such as stone, snow, and sand.  This way, when light passes over a material, the flecks would illuminate the way snow, sand, and certain stones do.

It will be great if you can share reference images to illustrate your request. Any image of materials with this effect will be helpful.

Thanks

Hi Baptiste.  I've attached an image of mica in sand.  What I have in mind is a filter that would allow for adding tiny flecks that sparkle when the angle of light is just right.
