Double layer blocks capable of turning endlessly

Abstract

Disclosed is a double layer block assembly comprising four single layer blocks, two first double layer blocks, two second double layer blocks, four outer stickers, and four inner stickers. An upper layer section of the assembly comprises two single layer blocks, two upper layers of two first double layer blocks, and two upper layers of two second double layer blocks. A lower layer section of the assembly comprises the other two single layer blocks, two lower layers of two first double layer blocks, and two lower layers of two second double layer blocks. The outer stickers are adhered to top and bottom surfaces of the assembly. The inner stickers are adhered between the upper and lower layer sections so that the assembly is able to turn about two parallel axes endlessly. A variety of shapes and colorful patterns for advertisement can be thus formed.
