If you’re interested in learning more about what HTML5 can do, you should definitely check out the demos Apple just released. (I shared some demos in my article on HTML5 and elearning but these are… let’s say… better curated than most collections.)
Now, Apple did choose to put up a browser sniffer directing you to download Safari if you don’t happen to be using Safari when you visit. I personally think Safari’s worth using for the anti-aliasing alone, but if you just want a casual glance, go to the developer section instead… The demos are easier to get to and most of them work just fine on Firefox.
And authoring tool vendors, please visit the developer section for the code. I would love for someone to make it easy for me to make really pretty HTML stuff. Just sayin’.
3 AM Update: I have no idea why I’m up this late, but I went back to the demos and the site has changed; now there are browser sniffers on each demo in the developer section, in addition to the one blocking the main section. And in all cases, they don’t just warn you that the demos won’t work… they prevent you from seeing the demos unless you’re using Safari. Way to show that HTML5 is a web standard, Apple.
The hospital I’ve been visiting lately has a great HIPAA job aid for its nurses and doctors: All of the public computers (such as at nurses’ stations) have screensavers with animations and text reminding them how to stay HIPAA compliant.
