Alright. This tutorial is much like the “Static Ball” one, but it has it's differences. I simply called this one Glass. Nice name, hm? o_O
Let's begin.

- Start out with a blank 300 x 300 pixel image.
- Color the background black using the Paint Bucket tool.
- Go to Filter > Render > Differencee clouds. Do the Difference Clouds 2 times. Not once! The second randomized filter is always better, somehow.
Alright. After this, go to Filter > Render > Difference clouds, using these settings: (Stroke length: 50.   Sharpness: 20.    Strength: 2)
Next, go to Filter > Brush Strokes > Ink Outlines, then apply these settings, and click OK.
Alright. Now, apply the Filter > Brush Strokes > Ink Outline filter TWO MORE times.
( Just click Filter > Ink Outlines. This automatically re-applies the filter, using the settings you earlier set for it. )
Ok! Almost done. Go to Filter > Distort > ZigZag. Apply the filter after adjusting it to the settings shown below.
Alright. You're basically done now. After applying the ZigZag filter, go to Filter > Blur > Blur. Giving it a blur smoothes out those rough edges.
This leaves you with the finished image. Congrats! d00t d00t.
