### About me

I am a retired mathematics, science, and programming teacher. I enjoy programming, fractals, and the mathematics of chaos theory. I am 80 years old and look forward every day to learning something new

### What I'm working on

My Scratch Blog:

www.scratch-blog.com

For the blog, I write detailed documentation for most of my Scratch projects.

I am currently working on the Harriss Spiral.
