In this episode we take a formula found on a Wikipedia page, and convert it into a Processing program that draws a simple flower. Ok, maybe you need some imagination to see the flower, but still.
The only new concept discovered in this episode is the scale() function, which modifies the coordinate system. This allows drawing larger and smaller figures without changing the x and y values used.
scale() can be used in conjuction to translate() and rotate(). All three functions modify the axes in one way or another.
