Today I spent most of the morning's work time on finding a way to replicate a glitter containing plastic (thought it would be cool if Blender could do that) and in the last tutorial, Procedural Textures - An Introduction, I showed an intro as to a possible method, but I was yet to fully give it a try and today I did and it looks fantastic.

You can see how it responds here. I rendered only a low res version that you can watch here, but this was just for fun, not work:
Glitter Material

Enjoy!

Thank YOU for the insight!!
