Phyllotactic model in 3D. This computer artwork was produced using PhylloTrees software and is based on phyllotactic patterns found in nature. Phyllotactic patterns contain opposing sets of spirals, the number of which follows the Fibonacci sequence and are observed in plants such as sunflower florets and pine cones. This model contains a single root node followed by branching daughter nodes (coloured cubes). PhylloTrees is able to alter the angle between nodes and the distances from the parent node to create a large variety of phyllotactic patterns in 3D. Such patterns may be used to visualise complex sets of data such as files and folders on a database. PhylloTrees was created by Petra Neumann and Sheelagh Carpendale of the University of Calgary, Canada.
