It was a party-like event in which people with different backgrounds and areas shared ideas and experiences of Scratch.
100 participants gathered at "Party of the Future 2009", a Scratch Day event in Yoshino, Japan, on May 3, and created this Scratch project. Their handwritings with a revision of Japanese traditional brush called "Yubifude" are used in this interactive animations. The animations were designed using the Scratch sensors to respond to sound, electric resistance, lights, etc., so that everyone could collaborate to get the animation
going with hand-clapping, hand-shaking, etc..
To try this project, download it and try with a PicoBoard connected.
