Was not easy to take a decent screeny but here’s my pixelated face. This is a WebGL demo that
uses the Mediastream API to retrieve user webcam stream. The stream is then proceded to detect movement and a GLSL shader pixelates the final image.
You can launch the demo from this page: Chrome Experiments: Pixelate Yourself
You can find more web-based apps on the author’s homepage.
