Pixel Unit Principles

This is a lecture only (PowerPoint slide show) explaining the history of pixel units (which were invented by the now deceased Max Hulme of the UK). Examples of pixel unit origami can been seen on my home page [ https://avanmeul.github.io/home/#secOrigami ] in the origami section (in particular there is a link for my PCOC 2017 gallery).
This class is highly recommended for those that will be taking my Pixel Unit workshop, and is also useful for those that will be taking my “Best Bar Envelope” class.
