  First plot on my #AxiDraw was successful!
  
  This is a sha256 hash of my name, each ring represents 4 characters of the hash.
  
  A hash is a transformation of an arbitrary-sized value into another value of fixed size. Hash functions that are one-way, i.e. cannot be reversed, are the basis of modern cryptography and security on the Internet. Given this image, you wouldn't be able to reverse it to find out the original string, but every time I run the hash on the same string it will output the same value.

  My first attempt at computational line art!
  
  This image is a representation of a sha256 hash of an input string, my name. Each ring represents 4 characters of the hash, and is the binary representation of the character's ascii value.

  The next step is to load this into my #AxiDraw and plot it on some actual paper!
