Alex Varanese has made a short video that's essentially stop-motion pixel art! If you like shooters such as R-Type (one of the games Varanese said inspired this), then you'll totally dig this.
Check out this short documentary about pixel art by animator Simon Cottee; in his own words it explores "the merits and impact of pixel art, animation and chiptune music". It contains a few interviews as well as showcasing snippets of several pixel art games and videos.
My friends Guy Collins and Leslie Wai recently collaborated to make a music video animated entirely in low-res pixels. It's pretty nifty. Go check it out!
