Fibonacci Tree Blue Green BEA0485 Image Mission Mokkyosha The Fibonacci Tree, designed based on shapes found in nature (Fibonacci numbers), transforms instantly into a spiral or pinecone shape just by rotating its axis left and right. Its sophisticated design makes it ideal as interior decor. The Fibonacci sequence is a series of numbers where each term is the sum of the two preceding terms, such as 0, 1, 1, 2, 3, 5, 8... It is named after Leonardo Fibonacci of Italy. Fibonacci numbers are famous for appearing in various natural phenomena, such as the spirals of sunflower seeds, the arrangement of flowers and leaves in plants, and the way leaves are arranged to receive sunlight evenly. This Fibonacci Tree was designed by John Edmark in 2008 and commercialized by Beyond 123 in 2016. [Contents] Main body x 1, Dedicated stand x 1 [Age Range] 9 years and older [Size] 12x26.5x12cm
