Recently, Mozilla upgraded the sound API they use in Firefox. Especially if you’re a web developer or a games developer this will be great news.
To show off this upgrade, Mozilla have also posted a small little tech demo called Songs of Diridum. If you use Firefox on your PC or Mac, you can access it by clicking this link and then clicking the “Play the demo” button.
The demo will put you in a virtual world, where the music gets louder or softer depending on how close or far you are from the virtual band. From your computer, you can navigate by using the arrow keys.
