this one is for the markup nerds
The image below might look like a regular YouTube video player but the interesting part is that the YouTube video clip will play just fine even if you disable (or completely remove) the Flash Player from your browser.
How? The next major release of HTML, dubbed HTML 5, will include several new tags for embedding <audio> , and <video> as well as several other graphical types of content in web pages. These new tags will let you play video files in the browser without the Shockwave Flash plugin. Yay!
Currently, your browser needs a plugin to play embedded multimedia content. For instance, you need to install Adobe Flash Player for watching videos on YouTube while the QuickTime player is required for viewing movie trailers that are available on the Apple website.
Visit youtube.com/html5 to see the HTML 5 video tag in action.
Note: You need either Firefox 3.5, Google Chrome or Safari 4 to view this video. If you attempt to go with an older browser, it won’t be able to understand the content that’s wrapped inside the <video> tag. You’ll most likely get some kind of error message upon arrival. That said, HTML 5 still looks very interesting and exciting.
