Ben Cohen of Ben & Jerry's encouraging Rubber Stamping Paper Money with Occupy Message.

I really like this idea; basically an ad campaign on the highly circulated dollar bill. 

Yahoo! News reports that Ben Cohen, co-founder of Ben and Jerry’s Ice Cream, is teaming up with Move to Amend to “distribute rubber stamps with anti-corporate election spending messages so that the politically-minded can mark their dollar bills.” Cohen plans to put a giant stamping machine on a national tour in August to encourage "thousands of people to buy rubber stamps and stamp any currency that comes into their possession."

Slogans like “Corporations are not people,” “Money is not speech” and “Not to be used for bribing politicians,” will now adorn currency in an Occupy cash campaign. The goal of Move to Amend is to secure a constitutional amendment that says “corporations do not enjoy the same protected rights as individuals and that money is not a form of speech.” Cohen’s attorney says that as long as the bills are still legible, it is legal to put the stamps on them.
