# 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.

But it was an accident. It creates a disappointing one almost every time.

Make curve smooth. It seems like a flower.

But I felt something boring.

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

...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!

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

## The 'Processing' code example.

Please feel free to use this 'Processing' example code under the terms of the GPL.
To see other works based on my code is my pleasure. And my honor.
