The US$59 Poppy lets you create and view 3D photographs on your iPhone. As the company puts it, “Poppy uses mirrors to capture photos and video at two slightly different angles. When you look in the viewfinder your eyes each see different photos that your brain combines to make really awesome 3D images.” It’s like a View-Master, repackaged for the 21st century. Users can share their images via YouTube.
