Yes, I think the flakes.osl in your normals channel will give you what you're looking for.
If you are using Standalone, I think you need to download one of the plugin installers to get the OSL scripts. At least the Standalone installer images I have don't seem to have them. In the plugin folder, there should be a resources folder, something like, "res/osl_scripts/pattern/flakes.osl", in the case of the C4D plugin.
In Standalone, you'd add the OSL node, Textures>OSL Texture, then either directly in the Inspector panel, or in the OSL Editor window, use the "Load OSL Code" button to navigate to the script you need.
