Besides the fact that this is a very impressive achievement, I also found it particularly refreshing because it was done in the nitty gritty of the street, not like a fake drawn background. It gave it a realness quality as you can observe stuff like real people blinking by (and I wondered whether they looked at some of the more bizarre graffiti as they walked by and what they thought of it), and you can see a dance of sunlight and shadows, the sky and lighting/weather changing, and it just was interesting to see how the art characters just did their own thing in spite of the whole world morphing constantly all around them. Although the art did a fair share of morphing on its own :)
And this may be a bit off topic, but one reason I point it out is that I often find myself just wanting to stare at things outside. Being in a fake plastic and "controlled" and "clean" office or home environment makes you forget how messy, detailed and interesting nature is, or even things built by man that are succumbing to forces of nature and environment - like those walls, bricks, ground, etc in the video. Even the dirt and litter on the ground kinda give an impression of this "realness" of a city, where people live, and it gives it like a real quality because it wasn't just some pre-designed background, it is real, it's just there, hanging around, being blown by the wind, being changed and morphed by the elements. Anyway I can't explain why I find that interesting, but that real setting is part of what made me so enthralled by the video.
