In 2011, I gave a talk at the TEDActive conference in Palm Springs, CA. For many years TED Active ran concurrently with the main TED conference, with special programming and simulcast TED talks. I presented in the TEDYou segment on the topic of ‘Metacities’—where real-time data converges with the build environment. The talk featured images and videos from several of experimental data visualizations, including my projects Pastiche and Invisible Cities.
