The Nintendo 3D comes up with 2 outward lenses and 1 inward lense for taking pictures and it is compatible with 3D graphics sans glasses. With outward lens you can take picture of any person and at the same instant the user’s picture can be taken with the inward lens. It is possible to combine two images and produce a single one. Users cartoon avatars automatically created by 3DS. It also enables users of 2DS for communication. With the help of tag mode, you are able to get the details of another user of 3DS, like you can come to know about the games he or she played last.
