Fading springboard icons?

[joshellis625]

Has anybody else noticed that when you don't use an app for a long time like Notes or something that it will start to fade or get darker. I thought I was imagining it at first but it kept happening. After opening the app the icon went back to it's original "brightness" level so to speak. Am I just crazy or do the icons actually do this?

Unjailbroken 2.2.1

I've only seen it once on the notes app.

Stocks, Notes, App Store: Haven't been opened for as long as I can remember. They're looking the same as they always have.

Cool idea though. It'd be great if they'd just vanish after this much inactivity.
