cool and very original 
Animation of a growing plant which consists of several branches. Each branch shows a number of leaves and flowers which can be set by the user. This demonstration can use two flowers and the leaves. You can arrange the plant branches in different ways and you can design your own sets of leaves and flowers. Instructions for using the plant animation for your own projects are included in a readme file.
