This digital agency named Breakfast created an Instaprint software that allows Instagrams to be analyzed in real-time for color, hues, and shapes, allowing large scale mosaics to be created.
Images that have been tagged with a specific event’s hashtag are analyzed by the software and assigned the best spot in the image being created. The images are then printed out on specialized printers that allow a crew to constantly be placing new images into place on the mosaic.
I think the fact the people need to put the picture manually is both labor-consuming and poetic at the same time, so I am not sure if it is at good or bad aspect. But the final result seems very compelling and creates a good background mood for the crowd.
