Nice, but short.
I liked this a lot more than most random line FBF's - mostly because you added in the glow effect behind the lines, which made it look a lot more interesting than just plain lines. It just goes to show how a little bit more effort can really improve a flash.
As for the length of the submission, it could have been longer, and I was actually disappointed when it ended slightly prematurely, because I wanted to see more. Maybe your next one could be a bit longer, with different colored glowing lines, and more of them at once making some more complex figures and shapes?
My friend experimented with 'drawing with light', which involved setting up a camera outside in the dark, and 'drawing' with a torch in the air using a 5 second shutter delay (I think that's the correct terminology - I'm not a photographer). Anyway, the results were quite spectacular, so perhaps something like that could inspire you as well for something really new and different.
