It's only a Commodore Vic 20 implemented in Javascript. With preloaded games. Wow, where did the past hour go?

"This rendering of iPhone 4 and its icons was made in pure CSS3. No images, no base64, no SVG, no canvas, just 3395 lines of CSS code and 335 lines of Javascript code (with jQuery, of course)."<br />You can unlock it, turn it on or off, and use the Home button. Does this count as <a href="http://en.wikipedia.org/wiki/Skeuomorph">skeumorphism</a>, though?

"I made CSS3 progress bars for a display of data inside localised leaderboards for the new analytics platform at <a href="http://g5platform.com">G5</a>.<br />"They are light-weight, requiring no Javascript. They look great on iOS devices and they're incredibly simple to use and customise. No images are used."<br />"These progress bars are <a href="https://github.com/jsullivan/CSS3-Progress-bars">free to download at Github</a>."

"CSS Shaders is a new feature folks from Adobe, Apple, and Opera have proposed to the W3C CSS-SVG Effects Task Force.  Rather than being limited to pre-canned effects, such as gradients and drop shadows, CSS Shaders would let web developers apply arbitrary OpenGL shaders to their content.  That makes for some really impressive demos.  Unfortunately, CSS Shaders has a security problem."

The explanation of the way that the security problem arises is very complicated, but essentially means your information could be leached.

Microsoft is dropping its own DX filters for CSS3 standard alternatives in IE10 (as it began to do with IE9). Essentially, Internet Explorer 10 is looking like the most standards-oriented browser Microsoft has produced since - and perhaps even more than - Internet Explorer 1.0.

Really excellent fun. Keep and study. Obviously, you'll need an HTML5-capable browser to see them.

Includes the CSS3 code. Works on Chrome, Safari, Firefox... and this one includes a moving version of Pong. Bookmark this one. (Makes an interesting test for mobile browsers too.)

"Sprite Cow helps you get the background-position, width and height of sprites within a spritesheet as a nice bit of copyable css.<br />
"Why? Automated spritesheet generators are pretty cool, but I prefer the control over optimisation and compression you get by making them manually."
