Researchers figured out how to use single "slices" of an image on an iPad to create 3-D animations that appear to glow in mid-air when you photograph them with a long-exposure camera. Watch a new experimental medium being born.
This video shows, without a doubt, the most magical thing I've seen the iPad do yet: creating a series of gorgeous, twinkling holograms, captured with long exposure photography as the iPad was moved through the air. Confused? Just watch.
