Lightning post-pro... I did this in Photoshop. It's still a rough image, but I think you can see what it ought to be. I rendered the lightning bolt (download from Brycetech. Thanks!) as an object mask and then cut them out and pasted them over the final image. Layer/Effects/Outer Glow. Turned the intesity all the way up and changed it to the color I wanted. Now I just need to tweak it a bit.
