If you missed the fireworks on the 4th of July this summer, this website from Washington D.C.'s Kennedy Center is for you. Art of the Explosion is a record of Chinese artist Cai Guo-Qiang's 2005 pyrotechnic work, The Tornado, that was created to launch Kennedy Center's Festival of China. On the site, visitors will find back-stage video, interviews, design sketches, animations, and other documentation that trace Cai's piece from conception to ignition. Intended for high school students, but perfect for all ages, the site also includes a create your own fireworks function, where you can arrange clips of different fireworks like rings, chrysanthemum, or Roman candle, on a timeline and watch them go off.
