How does highlighting only part of the hovered element help to "elevate" anything?
You either apply this affect as subtly as chrome; then it does nothing for usability (neither positive, nor negative).
Or you apply it as visible as in this blog post; then it's distracting and hurts usability.
Either way I can't see why you'd bother. Unless you're a bored google chrome engineer...
The page itself confused me though as I thought the inline images were meant to be working demos and they did nothing for me until I went to the demo page itself.
[edit] fixed typo
The effect doesn't appear in either Chrome or Chromium for Linux or Windows.
