The forthcoming HTML5 update to the 20 year old HyperText Markup Language promises to bring the "web" experience to a whole new level, allowing the browser to do more from both a visual and data perspective. Even though HTML5 is still a good distance away from being fully deployed, that hasn't stopped many developers from pushing it to the limits.

Check out these amazing websites which really give you a good idea as to the capabilities of HTML5 as a programming language, doing things in your web browser that were once only possible in an external program or plugin. I've tested them in Chrome and they should all work in an HTML5 compliant browser such as Chrome, Firefox 4, Safari or IE9. They are demos and HTML5 is still a work in progress, so if you have problems viewing them you might want to try in another browser. Enjoy!

8-bit Color Cycling (Like Old School Games)

If you were a gamer in the early 90s you will remember this effect fondly. Since computational power was limited, graphic designers used 'tricks' to emulate video in a static image. This canvas effect will show you how it was done and also includes many examples which are beautiful as well.
