Pixel art, as a form of creating a bigger picture out of small details, was born in the 1970s, when computers and digital art started to gain relevance and, as you can guess, it is based on pixels. For those familiar with the term, but unfamiliar with its graphic characteristics, a pixel is like a cell in a living organism - it is the most basic structural unit of a digital image (and hence the name: picture + element = pixel).
