currently used for pageantry and special events by China, drone laser light cluster shows may eventually approach the resolution pixel dimensions of a color tv flatscreen the size of a jumbotron at a football field. currently a closely held government secret is that such projections can be used ostensibly in international communications such as across foreign borders to disseminate propogranda or warnings directly to the domicile citizenry of another sovereign country. assuming that the conventional flat screen television is on a scale of 1920x1080 resolution at a viewing distance of a football stadium or ballpark view the size of a jumbotron such as at tampa bay stadium is 60 feet by 160 feet wide there would have to be 2,073600 drones lit to fit the resolution aspect.
