Nihilogic: Sandbag text wrapping with Canvas

"With CSS you can make text wrap around an image using the float property and for most purposes this is quite adequate. However, it doesn't take into account the actual image and treats it as one big block, even if you'd prefer the text to wrap around the actual content in the picture, magazine style.Since we now have pixel access (in cool browsers, anyway) via the Canvas element, this technique can now be implemented dynamically with a bit of JavaScript."
