HT to Laughing Squid for referring me to this cool Tumblr:

Noirlac, a Paris-based designer and Ubisoft video game developer, uses screenshots from old video games to create pixel art animated GIFs that highlight specific details within the image. Some of the GIFs are so subtle it’s hard to detect movement at all, while others are extremely bright and flashy. For more animated landscapes, characters, and enemies from classic video games, head over to Noirlac’s Tumblr.
