Reactive Fractal Viewer
"Mandelbrot Fractal Explorer is the smoothes, fastest and most reactive fractal viewer on the web. Creating a fractal visualization is CPU-intensive, and we want to be able to navigate our visualization at 60 frames per second on low-end smartphones.
This application solves this problem with a system of tiles that are instantly scaled in CSS when zooming, while waiting for higher-resolution tiles to be computed asynchronously by a pool of web workers."
