This texture was generated in Filter Forge, a Photoshop plugin that allows you to create your own filters.
I was working on my marble when I discovered this.
*Hints:
You could create water and liquids if you played around with it long enough. To blur out some of the shiney effect just move the take out shine slide.
If you want more shiney like texture then just move the reflectivity slider.
water, liquid, chocolate
