Abstract: A structure comprising a plurality of regular hexagonal tubes and a plurality of rhomboid inserts is disclosed. At least one of the tubes can be placed end-to-end relative to another of the tubes in a configuration where the central axes of the tubes are parallel. These central axes can be either collinear or not collinear depending upon the overall configuration of the structure chosen. Each rhomboid insert fits inside at least one section of a hexagonal tube. Those rhomboid inserts that fit into more than one hexagonal tube provide a means for interlocking the tubes.

Abstract: The present invention is an illuminated container holder for displaying messages and having an upper retainer, a lower retainer, a base, and a handle. The upper and lower retainers are configured to hold a container and the base is configured to receive a container bottom. The handle includes a power source and switch for powering a first and second light source. A container gripper is coupled to the lower retainer for gripping the container. The upper and lower retainers are designed to serve as sleeves for receiving and displaying messages or designs printed or inscribed on transparent material, wherein the messages may be electronically displayed or controlled. The first light source emits a light into a container receiving area and the second light source may emit a light upwardly into the container receiving area, or downwardly toward the ground, for example.
