I like chemicals! A talk related to my forthcoming book Molecules

I gave a talk that I rather like at a conference called The EG in May 2014. The first few minutes are a sort of recap of the history of The Elements app and Touchpress, but then I launch into talking about Molecules, my new book coming out in October, 2014. 

Here's a video of the talk:
