The way I made the petals was with bezier vertex in Processing. I set the first point with vertex() and then let the programme randomise some of the other points like this: | The way I made the petals was with bezier vertex in Processing.

bezierVertex(i-random1, i-50, i-random1, i-150, i, i-200); | bezierVertex(i-random1, i-50, i-random1, i-150, i, i-200); | ||

Here the starting point for the form is i, i. The 1st and 2nd values are the coordinates for the bezier handle that starts from the starting point in vertex(). 3rd and 4th and the second bezier handle's coordinates (that are attached to the finishing point) and the 5th and 6th values are the x and y of the finishing point for the line. So these two lines are the two sides of a petal. For each flower in the programme I set different random values, because I didn't want any two flowers to be similar (the programme randomises the value only once, so random1 value is the same for each random1 used in the code.) With the rotate-command I rotated the petals so that it created 6 of them. | Here the starting point for the form is i, i.

After I had tested and tweaked the code to my liking I got out the flowers I had in mind. Here I had already set the colours to what I wanted: | After I had tested and tweaked the code to my liking I got out the flowers I had in mind. Here I had already set the colours to what I wanted: | ||
