This is a set of interactive "Magic Cards". You download an app to your phone or tablet. Then aim your camera at one of the museum cards. The image automatically appears in 3D right off of the card! By moving your phone and by using the touch of your finger, you can move and rotate the 3d image to see it from any view and also enlarge it for more detail! There is also automatic narration (in Chinese) that tells about each cultural relic. The "Magic Cards" in this collection are from Emperor Oinshihuang's Mausoleum Site Museum. There are 24 cards of 24 different cultural relics. It is a used set. A few of the cards have bent corners but this does NOT affect the ability to view any of the relics in 3D. I have tested these and they work wonderfully! You can see a fair example of how this works at: http://www.zhichu99.com/a/p... This item is listed on multiple sites.
