I used two different pedal curves in this project. One of them I managed to use MouseX to control the n number of the pedals, while the other one I set the n number to 3 to create the two-pedal peach shape. Moving the mouse from left to right will increase the number of pedals from 0 to 5. MouseY controls the size of the peach.
