I love this video Pendulum Waves" from Harvard so I add sound synchronized with this movie. I made the Pure Data patch that simulates pendulum motion using formula of it. This is my first responsing movie. Please check out the original video. http://www.youtube.com/watch?v=yVkdfJ9PkRQ Harvard Natural Sciences Lecture Demonstrations http://tinyurl.com/3ee2eya Pendulum Wavesに感動したのでPureDataでパッチを作って合わせてみました。 比較的きちんとシンクロしています。
