Quirksmode is seeking to raise € 2,500 in donations
I have no idea if this is going to work. I’ve never tried it before. But if I never try I’ll never know, so here it goes. And I’ll give you fair warning: there’s a blackmail aspect to all of this.

The State of HTML5 Audio
When I started to work on my JavaScript Game Engine back in October 2009, the biggest problems I encountered were with the new HTML5 Audio Element. The Canvas Element already worked nicely in all browsers that supported it at the time, albeit some were a little slow.
