From npw, comes a really cool way to sketch and draw with these 3-D Drawing Pads!
Just draw, sketch, or jot down some notes on the pad and then put on the 3-D glasses. It's so awesome, we love it!
Here's the science behind 3-D Imaging, also known as Stereoscopy:
The lenses filter out all the red & green or red & blue colors (depending on the glasses) from the image, which means you can't see the entire pattern. The black ink that is used to draw the image can still be seen very clearly and appears to be in the foreground. It looks like it's floating in front of everything, giving the image that 3-Dimensional effect we all know.
