This is something I made that i thought looked pretty cool. I called it Red Vs. Blue.
This tutorial is how i made the lightning in the background:

To create the red and blue balls i went to filter>Render>clouds and than >filter>distort>spherize. I put the Spherize on max and than cut out the center ball. I just changed the colors and added the white lines to look like the balls were "cracked" or "shattered."
