Been doing some courses on Coursera of late. Leading Strategic Innovation is a great overview of the constraints that hold back innnovation and what can be done to counter them. The course is basically the innovation part of Vanderbilt's MBA programme, complete with group work done over the net. I highly recommend them.

been thinking about over the last few years and inspired me to make the
Human Made Digital Reflection on the videos page.
