A single wooden panel packed with a whole afternoon's worth of busy hands. A large round wheel spins on its center, tiny metal balls trapped inside rattling and clicking with every turn, while two smaller pinwheel gears mesh together and spin at a touch beside it. A small mirror panel swings open and shut on elastic bands, hiding a peekaboo window behind it, and further down, a color wheel spins to reveal glimpses of a different painted color through holes cut into its face. Off to the side, five smiling wooden knobs slide along wavy channels routed right into the wood, tracing curved paths that cross and dip as small fingers push them from one end to the other. Standing upright on its own built-in leg, the board turns any patch of floor into an activity corner, gathering turning, spinning, swinging, and sliding into one compact piece. Each activity rewards a different motion and a different sound, keeping a toddler's hands and ears both engaged. Sturdy wooden construction stands up to enthusiastic hands. For ages 1 and up.
