This is actually an 800 x 600 portion cropped from a 2048 x 1536 image that was rendered with the Upscale function.  The Spray Tool applied tiny Globule style droplets with Colorized Shading activated.  The Stylus Tool using the Fang Pull Method skewed the droplets.  Then the Stylus Tool with the Expand Pull Method was applied twice over the whole image, first up and down, and then back and forth.  This sequence of steps is preserved in the ExpandGrid Script.  Saved Scripts can essentially serve as a sort of repository for interesting manipulation sequences.  Script segments might later be spliced into new Scripts, parameters might be tweaked, steps might be recombined in various ways, different source images might be used, etc.
