This Liquib image shows multiple Grills and Shatters applied with the Mesh Tool.  The Grill and Shatter Mesh Methods are generated around the point where the mouse is initially clicked and held down.  The mouse can then be moved down or up to grow or shrink the area covered.  With the Grill Method, horizontal mouse movements will twist the radiating strands clockwise or counterclockwise.  For Shatters, horizontal mouse moves will produce entirely different variations of the strand structures, some with holes in the center (perhap caused by bullets).  The two strand colors are blended from inside to outside with Shatters.  For Grills, one color is used with the concentric rings around the center, and the other color tints the strands that radiate out from the center.  Strand Thickness and Density can be adjusted.
