The work of John Smith should require little introduction from me – he has contributed hugely to the study of many aspects of origami, not least of which was the COET (Convention of Origami in Education and Therapy) event.
We have spoken frequently in the past on such esoteric topics as “pureland” and “origami beauty” and although getting on in life, he remains one of the foremost “origami thinkers” of our age.
His latest offering is a document on “Simplicity and realism in Origami”. Fascinating and intriguing material! You should also browse around his amazing site.
