  much more impressive drawings have been created than this.
  The added animation doesn't add much.

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.

You could be right. I wouldn't conflate "novel" with "new or cutting-edge" (one can still do novel things with old tech) but even just limiting it to novel may be unfair. I guess this is just something I associate with HN submissions from experience - many things posted here really genuinely blow me away. This didn't. The normal reaction to that might be to just say nothing, but given the browser support issue, I commented.

Given that I was additionally mis-attributing the non-cross-browser functionality to the author (see edit - it works fine in Firefox), my own subjective reaction to it is probably that little bit more unfair again now.
