Hatsune Miku in the clouds

Here’s a video of vocaloid Hatsune Miku being projected onto sky clouds all in the name of the Kumo Project. The project has been set up as a study into clouds and the prediction of the meteorological conditions to progress this kind of technology as well as better understanding the development of the equipment to make this a possibility. So essentially a study into what technology, equipment and cloud formations are required for optimal cloud projections? Rock on Japan.
