Game Developer Gives 7-Year-Old Best Birthday Present Ever
Apologies for the meta comment but this is the thread with the highest points/comments ratio I've seen in HN. Almost six hundred readers upvoted it but less than 10% posted a comment, which is pretty unusual. I'm guessing it's the overwhelming "this is amazingly cool/touching/lovely but other than I don't really have anything to add to the discussion" feeling.
