The Sideways Dictionary's goal is to make complex-sounding tech terms easy to understand through analogies. It was created by Jigsaw, a Google-backed company of engineers focused on social good in repressive countries, and The Washington Post. The dictionary is filled with terms like "Secure Socket Layer" and "API" which are important things to know but can be hard to explain.
Using crowdsourced analogies, which can be voted on by users, the Sideways Dictionary breaks these tech terms down into ideas anyone can understand. The dictionary's website is wonderfully minimalist, with a single-page design that eliminates the need to search for a word or term. Jigsaw says it hopes the Sideways Dictionary will make the tech that people interact with on a daily basis (and in most cases depend on) easier to understand.
