摘要:
An ornamental compass comprises an ornament such as a doll or car. The ornament is attached to a direction-adjustable means which makes the ornament easy to be adjusted and pointed in right direction. The direction-adjustable means is connected to a magnet. The magnet is powerful enough to make the ornament, direction-adjustable means, and magnet point in a direction. A rotatable means for supporting the ornament, direction-adjustable means, and magnet fluctuate in any direction, which fluctuation gives the ornament an interesting movement.
