Think of frosted bathroom glass - light clearly passes through, but it doesn't come straight through - it gets scattered and bounced about, so the resulting image is just a big blur. The same is true of a translucent material, such as the foam sponge shown in the picture. Theoretically, it ought to be possible to unscramble these light patterns, to recover the original image. It may even be practical with something like bathroom glass, where the peturbations are at a fairly large scale. As for the sponge, I'm doubtful they could measure it accurately.

Anyhow, bending the light .. making it go the way you want it to go .. at least, that's the picture I get from it. Now, makes me think of people who can see through clothes .. hm .. how come ..
