Klimba is a new musical marble run from Switzerland, using wooden blocks and ramps in combination with xylophone keys.  Different length ramps allow for 1/2 notes, 1/4 notes and 1/8 notes, so it's not only a marble run, but allows players to create specific melodies.  Klimba Creative has 40 pieces.

Visit Klimba's home site in Switzerland for additional images and information.  Ages 3 and up.  CAUTION:  Marbles can represent a choking hazard to very young children.
