I have read about this Idea in India, an NGO called FPI set up to fight corruption has printed over 200,000 zero-denomination notes that resemble Indian currency and has begun distributing them around the country. It is asking people to give the notes to anyone demanding a bribe. This is their promo:
"Imagine that you are going to a government office to get some paper cleared or some certificate and the lazy guy out there refuse to give you the stuff as promised and ask you to come back in another few days, weeks or months. You know that he expects you to pay bribe and you really don’t know what to do. So how would you handle such a situation? You want to yell at him, but you don’t know how to express your anger. Here is a solution: The Zero rupee-note."
Do you think it can work in Egypt, or since the pound is already of Zero value, it doesn't matter much.
