Some kids like to draw patterns and pictures on the wall or the ground when theyre playing. This has a negative impact on the environment and is often difficult to clean up. This product is a portable toy, which can project images, e.g. the graphic patterns of different games that children like to play. Children can control the game by turning the ring. The patterns can be downloaded from the internet.
