发明名称 Clepsydra decoration set
摘要 A decoration set includes a transparent container having upper and lower terminal portions interconnected to by a slanting middle part. Each of the terminal portions defines a reservoir adapted to carry a sandy medium stored within the container. A board is mounted within the container and includes opposing sides provided with rippled surfaces which cause a decorative pattern as the sandy medium flows thereover. The container can be oriented in a first upright position wherein the sandy medium flows over the rippled surface causing a pattern on one side of the board and an inverted, upright position wherein the sandy medium flows over the rippled surface causing a pattern on the other side of the board. The side surfaces also include vents through which the sandy medium flows.
