Conference tutorials
I have given two tutorials and one public lecture at the International Conference on Liquid Crystals (organized by the International Liquid Crystal Society), once in Keystone in 2006 on dielectric spectroscopy, once in Mainz in 2012 on polarizing microscopy, and most recently on how to give talks in Kent in 2016. You can download the screen recordings here, generally with the live audio from the tutorial. In the 2006 tutorial I recorded the audio after the conference, so the audio is a bit better there (but the instructions concerning moving within the tutorial are no longer correct).
