HTML5 Blob

Today I made a blob in HTML5 canvas: http://www.byronknoll.com/blob.html

You can interact with the demo by moving your cursor. This is the second time I have made a blob. My first blob was for a game I made called Time Stop. Since Box2D has a JavaScript port, I was planning to use Box2D for this project (here is a Box2D demo in HTML5 canvas).

However, I decided not to use Box2D when I stumbled across this amazing demo: http://www.ewjordan.com/processing/VolumeBlob/. ewjordan discovered a technique for simulating blob physics that is computationally efficient (much faster than Box2D), realistic, and extremely simple to implement. My demo is basically just a port of ewjordan's Processing code to JavaScript.
