According to Wikipedia, TEDx talks "address a wide range of topics within the research & practice of science & culture, often through story telling. The speakers are given a maximum of 18 minutes to present their ideas in the most innovative and engaging ways they can." Since 2006, the talks have been offered for free viewing online through TED.com. As of March 2016, over 2,400 talks are freely available on the website. The talks given by academics are viewed more often online, while art & design videos are watched less than average.
Author Graeme Simsion gave an 18 minute TEDx talk on: "It's all Design, from IT Projects to the Rosie Project." View the video here: www.youtube.com/watch?v=dSA06HBdb8w
