That 'power saving feature' was the most irritating thing since pop-up advertising to anyone not using the mouse to scroll through.. I couldn't focus on the article because of the multiple interruptions and then the constant thought that I'd be interrupted again if I didn't move the mouse. Nice thought, horrible, horrible implementation.

Agreed, what a stupid thing to put on your site. It was enough to stop me reading after the first time it came up.

Just out of interest, is there any power saving benefit whatsoever gained from displaying black on a TFT screen? Surely the power usage comes from the back-light and that's on regardless?

Presumably it takes some (small amount of) extra power to download and run the javascript required for the effect so my guess would be that it actually increases power usage overall (a tiny amount, but still).

Black pixels on a TFT may even increase your power usage (they must be turned on so that they don’t let through any light), if only marginally.

But we will come full circle soon. OLED displays do need more power for white pixels than for black pixels.
