Notes:

You may have seen this one bouncing around on twitter in the past couple of days, it’s a lovely little experiment using <audio> & <canvas>. You can read more about it on the 9 elements blog. Thanks to Sebastian Deutsch for letting us know about it.

Unfortunately this screengrab doesn’t really do it justice so be sure to have a good play – http://9elements.com/io/projects/html5/canvas/
