Stereoscopy on DS - Version 2

Sylfurd posted this:

While playing Brain Training, I noticed some strange flickering effect on the text on the top screen of the DS ... What made it was the fact that when you look this screen from above, dark grays become black, and from below clear colors become white !
So i thought that if it was possible to make the left eye see only dark colors and the right eye only clear colors, it would be possible to display 3D stereoscopic pictures !!
