Tipp-ex:
Truth - People are scared to make mistakes.
Idea - Some things can be unsaid.
Strategy- You are the only one who knows your mistakes .
Print :
The goal for print is to make the reader question what was written previously.
This comes to show that mistakes are made however only you will be aware of them.
Experimental
There would be two walls in different areas of London were people could write their mistakes and then tipp-ex them out.
Social Media:
Tipp-ex would hijack twitter for the day and all users would be able to play around and delete certain words to change the meaning of the original tweet.
