Originally, the idea started as 2 sets of rings. One set was slightly larger than the other so that they could stack if the sets were alternated. The toy was fun, but we wanted to find a way to create stacking rings that didn't need 2 sets.

One day, while playing with the prototype, we realized that if the rings had a different geometry, they would stack when rotated. After that realization, it didn't take very much 3D design to create the Fibinacci rings. As we desinged the rings, we didn't have super specific measurements in mind besides making sure that the rings wouldn't be so thing they broke and that the most inner shape wouldn't be a choking hazard. That's why we were so surpised when we cut the pattern and something looked familiar. We finally did some measurements and realized that we had accidentlly created a pattern that followed the Fibinacci Sequence.

The shape was mesmerized and was so fun to play with. We experimented with how to router the sides and more efficient ways to cut the wood with the CNC, but we didn't any of the essential details about the shape

The final change we made to this toy was actually suggested to us from an online toy-making group:color. The original design for the toy was only with natural wood, but we had so many requests for color that we decided to try it out. We were IN LOVE with the result, and even though it was a pain to manufacture, we still love it.

We were really surprised how our girls ended up playing with this toy. We knew it would be an interesting puzzle to make all of the rings fit together and stack, but our oldest actually uses it for small world play as well. She uses it as a volcano, a mountain, and home for all of her animals.
