The Fibonacci Tower is not only an art object, but also an architectural model, a science toy, or an ornament for Christmas.

The Fibonacci Tower is reversible. You can assemble it either clockwise or counter-clockwise. It is very easy to assemble and disassemble. If you bundle the parts, they take up very little space. The assembled tower is a very elastic structure, balancing exquisitely without falling down.

This model was constructed with glue.
Your eye can trace many spirals on its surface, like a sunflower or pine cone. Notice that every spiral is based on a Fibonacci number. (The Fibonacci numbers are 1, 2, 3, 5, 8, 13, 21, 34... Each number in this sequence is the sum of the previous two numbers.) For every spiral, the difference between adjacent parts is one of these numbers. This pattern follows the same principle as the leaf arrangement of many plants. It is a very effective structure to reflect light or sound diffusely. This is a strategy of plants that you can learn through the experience of assembling the Fibonacci Tower.
