Flashing Christmas Lights is an interesting theme. It adds a string of Christmas lights around your icons. It does not mod your icons so, you are basically supposed to use it in conjunction with another theme. The string of lights will randomly flash in different patterns. In order for the theme to look exactly right, you will want to enable the Transparent Dock via WinterBoard. The theme seems to work very nicely, I did not have any issues with glitching. Though, I would image that it might drain your battery a little faster than normal.
