Find Hidden Ninjas in Stereoscopic Photos
This book can be downloaded and read in iBooks on your Mac or iOS device.
NINJAs are training in modern Japan, but they cannot be found in an ordinary way.
They will only appear when viewed as a 3-dimensional stereoscopic image.
A total of 8 NINJAs are hiding in seven of 39 photos.
Can you find all of them?
Though, you can use iPhone and iPod touch to enjoy stereo photographs, it's recommended to use iPad to view them with a larger screen for more dynamic effect.
