flatpack festival

To be honest I was rather disappointed with the flat pack festival, as I didn't see any animation, which was what I thought the festival was about. However, we did see some rather interesting things, such as a man who could write on paper without using a pen or any other writing tool. We each had a suggestion as too how he achieved it and came pretty close. My suggestion was he had some sort of device going up his sleeve, down to his finger and used heat sensitive paper.
