Collect all the notes to help Bach write a Sonata! It's fun snake game but with with that classic 8 bit sound. To use it as a 404 page, take the file 404.html in the dist folder and place it wherever you want it (cloudfront, your server, etc.). It has all the necessary files all crammed and minified/base64'd rigt into the html file.
One fun part of this lil' project was writing the note interpreter function that takes in an array of notes in the format Ab5 and plays the correct frequency on the oscillator. I had to learn a little about how frequency relates to note values :D
Clone the repo, then:
npm install
gulp develop
To build an updated 404.html, run gulp release.
