Over on his shiny new Tumblr, my good friend, fellow Sandboxer and fellow TEDxZurich organizer Thierry has a great wrap-up of what was certainly the most fascinating of the TED talks we've seen yesterday during the livestream: MIT scientist Deb Roy presented a project for which he recorded every sound and every movement in his house over the course of two years. With this incredible amount of data, Roy was able to virtually recreate situations like the time when his baby son was taking more than two steps at once - in Roys words, this is akin to "reliving" certain situations from your life.

I found the more subtle things Roy does with his data more intriguing - especially his demonstration on how a word is "born": Digging through his data, Roy extracted every instance of his son saying the word "gaga", which over the course of six months slowly metamorphed into "water". Hearing how a child learns a word in a 40-second time lapse recording is truly amazing.
