Literally..... designer Ricardo Seola created THIS educational music toy for children, that features a train that literally plays the track. The toy's track is designed with small bumps on it to pluck the metal keys on the train. The design borrows from the simple mechanics of wind-up music boxes and implements it in a whole new way. Because the track is divided into sections, children can rearrange them to change the song in new ways. The toy would feature multiple track featuring different songs that could also be combined to form even more musical possibilities.
