A new take on the traditional ring stacker, Tomy\'s Baby Vision Stacker is a bright, fun way to learn. The strong colours and different smiley faces in the middle of each ring provide visual stimulation, while the stacking action required to construct the tower aids hand-to-eye co-ordination. The modern take on the traditional toy is its stacking action--instead of a pole around which plastic rings are stacked, each \"ring\" has a half ball at the centre and a hollow base, so they fit inside each other. This means that the rings can be stacked two ways: in ascending and descending order of size. And though six-month-olds (the beginning of the recommended age range) won\'t be able to complete the stack, they will enjoy the wobbly base and surprise rattling smiley ball at the bottom, as well as the bright colourful rings.
