Abstract: A rotatable magic picture ball comprises a ball assembly comprising an upper section including four upper units and a lower section including four lower units wherein each unit occupies one eighth of a sphere and is rotatable, and each lower unit comprises a bottom cavity; a base assembly comprising four sectors each occupying about a quarter of a cylinder and a central recessed portion including two vertical sleeves and two horizontal sleeves, each sleeve having two channels for rotatably coupling the sectors together; eight half-circular stickers and two circular stickers adhered to inner surfaces of the units so that the units can turn each other; and an interior magnet on each upper unit so that two adjacent upper units can be magnetically secured together. A variety of shapes and colorful patterns for advertisement can be formed by the stickers having predetermined patterns and/or the ball assembly having a predetermined pattern.

Abstract: A shape-shifting game can. The game can includes upper and lower cylindrical blocks superimposed on each other. Each of the cylindrical blocks are quartered to form a total of eight fan-shaped columns and each of the fan-shaped columns comprise upper and lower fan-shaped surfaces, a circumferential surface and a pair of square surfaces. The lower fan-shaped surfaces of the upper cylindrical block and the upper fan-shaped surfaces of the lower cylindrical block are connected with fan-shaped stickers. Pairs of the upper fan-shaped surfaces of the upper cylindrical block and pairs of the lower fan-shaped surfaces of the lower cylindrical block are connected with hemi-cycle patterned stickers. The square surfaces of the fan-shaped columns are connected with double-block stickers. The circumferential surfaces of the cylindrical blocks are connected with four fan-shaped column stickers and two hemi-cycle column stickers respectively.
