Three-dimensional GIF?

This is behind a cut tag, because I don't feel like posting even a neutered ad into the middle of everyone's friends list. However, if you click on the cut tag, you'll see an advertising GIF that I found while browsing around tonight where the logo in the bottom right corner clearly appears to be in 3D -- at least to me! -- as I look at it on my LCD monitors.



Any idea how this works? As I move my head, the green "To" clearly shifts position relative to the other letters.

Or maybe I just need sleep.

That's interesting.

Actually, it turns out that I only see the effect when I'm wearing my glasses. My contact lenses are set to a slightly different focal length for each eye, so that one is better for distance, the other for close vision. And I no longer see the 3D effect with the contacts, nor do I see the 3D effect on the speedometer of my Ford Five Hundred except with my glasses.
