The folks behind the popular Weather HD app are getting into the holiday spirit. A set of New Year backgrounds is now available at no additional cost.

Available through Weather HD and Weather HD Free, the backgrounds, not surprisingly, change with the weather. First released in 2010, the universal app features live weather with 3-D NOAA Radar.

A Halloween theme was released earlier this year.
