DIY LED Rope light to create light art orbs.

Some of my favorite images are of light art using flashlights and long exposures to create some interesting pictures at night. I've seen a few tutorials on the new on how to create a light rope using LED's, which then can be used to make glowing orbs in photos. I decided to get out the soldering gun, and try one for myself. I changed the designs I saw to encapsulate the batteries and power toggle switch inside a babies bottle for better grip, and RCA photo plugs to enable changing LED colors in the field to be able to use the same power source.

Here is my first test shot standing in my living room, twirling the rope light and walking in circles. I'll need to tweek my technique, but think that this will work great this summer at a few locations shooting at night.
