Eliminate the blue outer glow in Exposé
One of the more questionable changes that was introduced in 10.6 Snow Leopard was a soft, blue glow that appears around application windows when using Exposé. Previously, in 10.5 Leopard, the entire Window was highlighted blue; now, however, the Exposé window previews are able to update their contents on the fly and obfuscating them with a blue highlight negatively affects the user experience.Unfortunately, the blue glow that Apple's designers have chosen to overcome this gap is somewhat garish and just plain lacking in style. In response, creativebits has posted a tip for changing that glow into something a little more eye-catching and a little less flashy.
The process is fairly simple and involves replacing two PNG image files within the Dock application. Creativebits has the full explanation as well as a sample set of replacement files that work pretty well and look very tasteful. Follow the break for a preview of the tip in action and decide for yourself whether the difference is worth the effort.

I like to blue glow too and prefer it to how it was done in Leopard.

It's been that way since 10.3, when Exposé was introduced. If you were playing a video and went into Show All Windows mode, the video would keep playing in its tiny window.
What I dislike about New Exposé is the non-uniform window scaling. It makes it harder to mentally track what is in what window. Completely breaks my mental model of my windows.
I read the comments on this post to learn how to evoke the blue glow. I am a heavy exposé user and the glow lasts about a quarter of a second on my screen at best -- hard for me to relate to the quibble but if I had to smell bell peppers for .25 seconds everytime I used exposé I would have blogged about it too.

Same here...10.6.2 2.8 GHz MacBook Pro.. no blue glow anywhere in Expose. Obviously it is not something everyone experiences....
