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.

I tried it on both a Princeton 19" CRT and an Eizo 15 inch LCD. I see no such effect. I notice, however, that all of the colored letters in the bottom left of the image have drop shadows which are often used to suggest 3-D depth.
