It looks easy enough but I think I'm incapable of easy things so late at night. I got a solid bar instead of separated lines, so I messed it up somewhere. After a bit of fiddling, I did figure out that you can do a similar thing using the Outer Glow. Made a short tutorial. I'm tired. In fact, I'm really really tired. I'm going to bed.
But thank you for the tutorial! Even though I'm completely inept, I did learn something!
