Musical Busy Boxes

CadenceViz Volume 7: Musical Busy Boxes

Ten bright busy boxes to entertain your toddler: diggers, fire engines, rattles and latches, every part moved by your music.

CadenceViz Volume 7 holds ten musical busy boxes: bold, friendly toys in soft colors, from a dinosaur at a lake to a backhoe in a sandpit, every part moved by whatever music your Mac computer plays. Each is a calm scene designed to hold your toddler's interest, its moving parts big enough to follow from across the room, and nothing on it flashes.

The busy boxes run on every Mac computer with Apple silicon chips.

Five of them optionally hold a place for your own pictures, which are read on your Mac computer and never sent anywhere.

Musical Busy Boxes offers a free download and 14-day trial period. Choose Volume 7 in the app's Catalog to start your trial. It costs nothing to start and nothing at the end. All 10 busy boxes are fully unlocked during the trial period.

Should you want to unlock Volume 7, a one-time purchase of $9.99 unlocks it for you and other Mac computers in your Family Sharing, or $29.99 unlocks all seven volumes and the Pocket Watch at once. If you already bought all six volumes at once for $29.99, Volume 7 is already yours.
