Nov 19th is IMD. It's been trending more in recent years, and has hit #1 on twitter trending for the last 2 years in multiple countries.

I'd like to step it up. How about something like we create fliers, and post them in different cities around the world at the same time? So these pictures of the identical fliers hit social media. Could generate a lot of attention and go viral even on reddit. We could have youtubers talk about us, maybe even the news.

What else could we do?
