Just press green flag to start making tree art. Use delta slider to control the height of tree. Use x-shift slider to control the width of the tree
You could do pretty weird stuff, try exploring all ways. The shape of the tree is always random no matter whatever you do! (I guarantee that the tree you made is unique and no one has ever made like that since the beginning of the time) If you are wondering what step is, its just counter of how many steps it did to make the tree. Every step it does the more time it will take to make further.
