3D Tech for PSP?

Irish optical technology developer RealView Innovations Ltd is planning to launch its new V-Screen for the PSP in time for the holidays this year.

V-Screen is

a unique 3 dimensional screen technology that enhances the perceived depth of 2 dimensional screen images

It's an attachment that "enhances the perceived depth of the 2D screen image" without the use of software or electronics of any kind, but apparently creates a fully three dimensional experience.

If that sounds kind of vague to you, then we are in agreement. I'm picturing some kind of overlay or second screen that somehow refracts or distorts the light coming through it to make two-dimensional images look 3D, but I really have no idea. I'll post more info as I get it. (Source: RealView Innovations press release.)
