While browsing the Web during an unofficial office break, I found this clever piece of street art or persuation art on BoingBoing. The "Make A Difference" poster has been designed by Imaginary Foundation (contrary to its name, the foundation is real), which has posted a PDF of the same for people to download and use.

The only problem with this kind of poster is that it will lose its uniqueness once all the "I Wills" have been torn. How will others display their approval? I tried to find some other solutions for such street persuation arts.

1. Use ribbons or laces: One can try placing ribbons or laces with a message along side such persuasion posters. People who support the cause can pick up a ribbon and put it on their shirts or bags.

2. Ask people to sign: Leave lots of space in the poster for people to sign the poster or leave a message.

3. Urge people to spread the word: A poster can also ask people to tweet or send a message to friends about their decision to support the cause. It will help spread the word as well.

What's your idea for a persuasive street art? Let the world know.
