Researchers have used soundwaves to lift many tiny objects at once before spinning and flipping them using electric force fields. The technology -- called JOLED -- effectively turns tiny, multi-coloured spheres into real-life pixels, which can form into floating displays or bring computer game characters to life as physical objects.
