Watching 3D movies often requires special glasses in order to see 3D effects. The true beauty of the cool gadget, Nintendo 3DS, is that you see in 3D without glasses! This feature alone makes the 3DS one of the coolest gadgets for kids. The upper screen is a stereoscopic 3D display, which provides objects within the game with a feeling of space and depth that, extends far into the back of the screen.
You can actually adjust the intensity of the 3D setting with the built-in 3D Depth Slider. You can even turn down the 3D affect completely. You can play all games and apps in 2D if you desire. There is a built-in motion and a gyro sensor, which react to the tilt and motion of the system. The motion compatible 3DS games respond immediately due to these sensors.
There is a lot of built-in software on the 3DS including: 3DS Camera, Mii Maker, StreetPass Mii Plaza, AR Games, Face Raiders, Activity Log, Nintendo eShop, Internet Browser, Nintendo 3DS Sound, System Transfer, 3D Videos and HotSpot Partners. The 3DS camera is actually two outer 3DS cameras which you can take 3D photos with, and there are a variety of lenses (such as Pinhole lens and Merge lens) to use to make some cool pictures with.
You can create Mii's with real photos or by selecting individual facial features such as eyes and nose. The StreetPass Mii Plaza is where all Mii characters go to meet and greet other Mii characters. You can exchange Mii data and gameplay information with other Miis.
Through the Nintendo eShop, you can purchase and download 3DS games right onto your console.
