Bret Victor invent tools for people. He’s a former Apple-employee, has written a highly praised essay on user interfaces called Magic Ink (which I started reading a couple of weeks ago), created the UI for Hipmunk and done a whole slew of other very interesting things.

His talk from CUSEC 2012, Inventing on Principle, got released on Vimeo today. It’s enlightening, inspiring, thought-provoking, educational and incredibly fascinating. I recommend you take the time to watch it right now.
