Encode a string of text in the ordering of a deck of cards.
I've always thought it would be cool to use a deck of cards to encode a secret message. This was a fun side project and a great opportunity to explore new front-end technologies. The result is a small web app to do the transformation of text to and from an ordered deck of cards.
- D3.js, a fantastic data visualization and animation library.
- Service Worker API, so it works offline-first.
- Web Application Manifest, so it can be installed like a native app and added to a device's home screen.
- Responsive CSS Sprites to save on HTTP requests and bandwidth appropriate to the user agent's pixel density.
- Webpack 2.0 so I can keep all my code in little files,
put my above-the-fold CSS in the HTML
<head>element, and webpack is just awesome in general.
The encoding process is Deck -> Permutation -> Factoradic -> Decimal -> Base 37 -> Text
