Don't like people watching you play yer DS? Get "privacy screens" and never be bothered by voyeurs again. For a couple years, Japanese companies have been selling this type of product for keitais, but not handhelds.

Put the clear film on both screens. Angle the DS thirty degrees or more, and the film goes black. However, hold the DS directly in front of you and see the screen no problem. That means Peeping Toms on the subway can't see how you're doing at Castlevania.

How does it work? The tiny grooves in the privacy screens are such that reflected light darkens the film from the side, but not for head-on viewing. Unless Nintendo is planning a slew of Peach and Mario adult content, this product seems better suited for PSP porn.

See it work after the jump.
