I am saddened to see that the submission has been flagged, as evidenced by the sudden plummeting in the ranking:

I know people's interests vary, and that's partly what makes HN interesting to me, but flagging this item seems at odds with the HN ethos of appreciating excellent work and amazing technology.
But there we go. It hit first place for a bit, so that affirms my belief that I do share interest and taste with at least some of the HN crowd.
Meanwhile, here's wishing everyone a Happy Perihelion.
