Interactive Art [Week 4] - Math Flower

Week 4 - Nature patterns 

For this project I took inspiration from the mathematical distribution of certain flowers and look up to a formula that changes the petals pattern according to a variable, in the first example the variable changes according to the value given from the slider and in the second example the value is a random number between the value of the slider as the minimum and 15 as maximum

  for(float a=0; a<TWO_PI; a+=0.02){
    float r = 200*cos(k*a);
    float x = r*cos(a);
    float y = r*sin(a);
