Glowform CSS3 Image-less Glowing Form Tech Demo
I wanted to see how close I could get with only CSS3 (and a little bit of helper JS).
This is the First Iteration
Checkout the demo (Webkit required. Though you can see an alternate implementation if you use Firefox 4, and non-animated mode in <4Firefox) [Not tested in IE]
TODO Writeup inset shadow mask technique, and more in-depth impl. info.
On Webkit browsers - I got pretty close, with color transitions and keyframes and using a background gradient animation to simulate the "highlight" textures.
Firefox doesn't support keyframes for the color transitions, so I implemented a used fallback animation with simulated color transitions. IMO the fallback animation on Firefox 4 doesn't look too bad either - with older Firefox's falling back to non-animated glow mode.
More variation in highlight and color angles
Dogfish has a much better variation of colors and highlight textures thank to the use of images.
Better browser support for animations
You could probably hack around Firfeox's lack of keyframe support via color transitions and classes.
