Well, in its defense, you can do things like this quite efficiently with WebGL or SVG. This is more of an abuse than a demonstration of the fastest-possible rendering in browsers. Similarly, my machine can't render a video into an ASCII stream into my resized-to-1-px-per-character terminal at full framerate; whether it can or cannot doesn't say anything about the state of playing videos on a computer.
If anything, demos like this serve more to demonstrate the capabilities of the system to people who may not be aware such things are even possible, not the best practices. This wasn't possible a few years ago in this way, period - now it is. Isn't that interesting and/or useful to know?
