Ed Spencer has created this canvas demo based on a screensaver found in OS X. The demo takes a set of images and then drops them on to the screen with a subtle semi-transparent rotating effect.
Comments from the Author:
Bean starts off with a blank canvas and a list of image urls, which it preloads before getting started. It then drops one image at a time, rotating it as it goes. Each falling image is called a Plunger, because it plunges.
Each Plunger gets a random position and rotation to end up in, and takes care of drawing itself to the canvas on each frame by calculating its current size and rotation as it falls away from you.
