Yesterday was the 23rd anniversary of the greatest tragedy in the United States of America. I'm not a big fan of talking about tragedies, but when I remember what happened to the twin towers, I feel sad because so many people died in that accident. But anyway, I've seen what Newgrounds users do on that day. They make art and animations about “Never forget”.

Even more to that, 9/11 heavily affected Newgrounds content in early 00's. You can still find the BBS posts made on that day.
