This is a easy, cheesy way to make a sort of cool electricity effect.
*Open Photoshop and create a new document preferably wallpaper size and make sure that your documents screen resolution is set to 72.
*Fill the document with black
*Pick out a favorite color and select it in your pallete along with the color White so your color pallette should look like this "Your Color/White"
*Now pick out a fairly large, soft brush, I used a size 150 for mine, and, using your color, not white, paint some lines either up and down the screen, or across... its your choice, but don't put them close together. make sure they're separated. (follow the animation if this confuses you)
*Now press "x" on the keyboard to select your white color. Either ctl+Click(Mac) or right click with your brush to adjust the size. On the size slider bar, take the slider to about half of your current size. Then trace the inside of your colored lines with the white. It doesn't have to be perfect, but it should be smooth
*Now press "x" again and select a brush half the size of your current brush and trace inside the white with your color. Once again, it doesn't have to be perfect, just smooth
*Press "X" one more time and get a brush half the size of your current brush and paint white inside your color. Doesn't have to be perfect, just smooth.
*Now, once this is all done, go to "filter" "sketch" "chrome" and move the detail and smoothness sliders to "10" then press OK
*Now you need to fade your chrome effect. Depending on your Photoshop version, the fade menue will either be under "Filter" or "Edit" Once you have the Fade dialogue up, choose either Overlay, or Soft Light. These will give you the best results, I used Soft light, but its a personal preference. The Opacity should stay at "100"
Now you have your creation. Its infinitely customizeable with color, lines, etc... so you could just play around with it and come up with something really cool later on.
