The Pixelator converts your images into an interactive canvas where you pixelate the image content through configurable layers. More fun than it sounds!
More About This Demo From The Author
The Pixelator is really a demonstration of the new imageData functionality within canvas. David Desandro wrote a JS library called Close-Pixelate, which does most of the heavy lifting in the demo: it's doing all the canvas manipulation. The Pixelator is basically just a user interface that allows you to dynamically construct your pixelated images through a simple series of layers.
This Mozilla demo has all functionality of the live site (http://thepixelator.com) with the exception of being able to save your images. See thepixelator.com for that.
