You say it's subjective, but when you start posting things like the above, you're deeming this project as unworthy of being on HN just because you feel it's "novel". The OP never claims the technology is new or cutting-edge, so why even bring that up? And there's really no need to link other css artworks in an attempt to undermine the work at hand. Why is this currently #6 on the HN front page?
Because someone took time to make this, and we tend to approach Show HN projects with an open mind.
