I stumbled on this on accident
Create a new document and fill it with color, or for the coolest effects, pick two colors using both of your current swatches in your tool bar, Under filter use Render: Difference clouds and watch the effect, Continue to press Ctrl-F until you see your desired effect.
Use Stylize: Stained glass with these settings
Cell size: 2
Border Thickness: 3
Light Intensity: 3
Apply the effect,
Again under filters use Blur: Motion blur, use the default settings.. or using the preview option tweak the settings till you like it.
Looks a lot like the underside of a beardie to me 
I'll post pics later.. Just thought this was fun for anyone who likes Herp related Website backgrounds and you have Photoshop.
