Defining Pixel Art

Dive into this nice read from Retronator on When Digital Art Becomes Pixel Art and prepare yourself for a high level look at the question of What is "Pixel" Art? Is it aliased blocks? Can it include vector paths ala RIP graphics? Is it vexels? Are they all just niches of the pixel art genre or is it something very specific?

Whatever it is, it's an excellent look at a bunch of work that was painstakingly drawn by Arvey Yudi.
