Abstract: A fibre optic display fashioned to illuminate an artificial Christmas tree utilizing a plurality of fibre optic filaments fashioned into a main bundle within the trunk portion of the Christmas tree. The base of the tree is supported by an illuminating base structure. A color wheel housed within the illuminating base structure is rotated by the heat obtained from a light source similarly housed within the base structure, interjecting various colors of light into the free end of the fibre optic bundle. The bundle is divided into branch bundles, wherein each branch bundle is secured to the trunk portion of the tree at the point adjacent the opening through which the branch bundle emerges from the interior of the trunk. The branch bundles run along the individual branches of the tree by being secured to the outside surface of the individual branches or by being confined within a hollow causeway within the individual branches.
