I’ve just watched High Score, a Netflix series on the history of video games which is packed with cool Pixel-Art cartoons:
During the documentary narration, viewers are presented with full screen (full HD) animations created in old-school Pixel-Art fashion, with the addition of a CRT monitor filter that give the impression you’re looking at an old TV screen. Of course, the actual pixels are blown-up in size to provide the pixel-art flavor, but the images are true pixel art (no sprite rotations shortcuts that break up the pixels’ orientation).
If you have a Netflix account, I strong suggest to watch the series (which you’ll probably enjoy for its contents too, since it deals with early video games from what we now call the “retro era”).
I wonder who drew the Pixel Art animations (didn’t dig into it yet).
