With 4 times as many pixels it makes much more complex animations possible, including scrolling text, and even low resolution videos.The bundled ninja diffuser makes the pixels look extra-shiny by providing some subtle diffusion, blurring the lines between each pixel. Simply use four of the nuts to space the diffuser slightly away from the HAT, and the other four to secure it.The MagPi said that Unicorn HAT HAD had a "real wow factor" and that the "performance is excellent" in their five star review
