WATCH: Join the "Occupy Your Block" Sidewalk Chalk Campaign

The Outreach Group at Occupy Wall Street NYC has an idea inspired by this story of unity between strangers using the original social media: chalk.

It's a creative, anonymous and exciting way for supporters of all ages to show support everywhere.

Join in:

1. Draw on your sidewalk a cool message about support for Occupy Wall Street, strength in the 99%, etc.

2. Leave chalk (maybe in a box) and write a note asking people to write on other parts of the sidewalk.

3. Take before and after pics, and send them to

4. Outreach Group will make a music video montage of all the pics sent in, post it and share it widely on for the new Occupy Your Block coming up in one week.

Nothing is more raw, more visceral than using rock on rock to communicate. Chalk has helped us launch major leaps in human evolution, perhaps more than any other tool; from cave drawings, to symbols, to language. It's a fast, guttural, fun way to share your voice with everyone who passes, and there's something about sidewalk chalk that makes every passerby want to take a look.

In a time when your message is either being ignored, ridiculed or demonized by traditional media, #occupy sidewalk may do the trick... Social media is anything but new.
