The tech is nice, but the art is incredible. Click the "Show Options" button and you will see the 8-bit palette animating in the lower right. The changes in the palette are the only thing causing the animation of the image. Instead of a series of images, there is just a single image and a function to modify the palette each frame. The artist picked pixels that not only look good, but also are coordinated with the palette and their neighbors to produce the animation.
