Creative coding pictorial flower.

How I made this creative coding artwork.

It's a creative coding artwork made with the 'Processing'.

I played around my other work Don't Count the Waves. And it creates an image like this.

 

Not bad.
But it was an accident. It creates a disappointing one almost every time.

 

Make curve smooth. It seems like a flower.
Not bad!

But I felt something boring.

 

So I gave a change with saturation and alpha by gradation.

Not bad, not bad!
...But it does not seem like a flower, I think.

 

I tried not to use blend(screen).

Ah! This is it! This is my taste!
I adjusted parameters, added a background to finish!

It so slow to draw. You might need a cup of coffee. ;-)

To see other works based on my code is my pleasure. And my honor.
