# Assignment #3

Fractals & Spirals

Using all of your pencil code and creative design abilities create a program that uses spirals or fractals to make a piece of modern art

![Navajo Indians Used Fractals in their weaving long before the math was understood](https://2507214486-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LpUPSf3tCxHePJxNjfg%2F-LzwKyYfpeaIRITklalG%2F-LzwLoAlnArhnVXG5Md_%2Fimage.png?alt=media\&token=6c0e5745-d3b9-416b-96f4-02837b061b09)

Requirements:

* [ ] at least 3 colors
* [ ] at least 1 random
* [ ] at least 1 fractal (object that you create that calls itself)
* [ ] should be amazing

Now- share your pencil code but this time use the **FIRST LINK  (see it  here)**

Then use the yellkey site to generate a yellkey that works for **24 hours** 

{% embed url="<https://www.yellkey.com/>" %}

Use your cellular device or a computer and check your yellkey to make sure it works

Next: Turn your yellkey into a QR Code & print it out.

#### Why did we do all that?&#x20;

Your homework (the only homework you will have in this class) is to take a photograph of a grown up looking at your amazing fractal program and bring in that picture on Monday on your cellular device or have the adult email it your school email or have a sketch artist recreate the moment or have  that grownup write a note to me about how amazing you and your program are
