What Kind of Photographic Trickery Is Going On Here?

Left side of the photo: adorable 4-year-old pancake chef is blinking. Right side of the photo, in the reflection: his eyes are wide open. Whoa. Viral marketing for the The Last Exorcist? Not exactly.

The prevailing theory, from BoingBoing commenter nickelrocket:

resolution pixels on the chip load from L to R (or R to L) and the split second refresh caught both sides of the blink?

Or the kid's just possessed. Any sharp commenters know for sure? [BoingBoing]
