After attending Una Kravet's talk on building a simple game entirely with CSS (codepen.io/una/pen/RVZvOy) at CSSconf EU 2017 in Berlin, I was fascinated by how generative Sass pixel art can be used to draw entire characters!

Inspired by her talk, I decided to give it a try and create Pikachu, entirely built in CSS—hence, I call it PikaCSSu.
