This Medium post gives a lot of detail about this project - all I want to say here is that this little book is full of wonders. It is a magical exercise in seeing rather than looking at the different types of interactions we engage in with our surroundings.

For those of you who are interested in purchasing the book, I have noticed it goes in and out of circulation - one time I saw it on Amazon for more than $500 (I got it on Canadian eBay for much much less but still rather pricey). Worth every cent :)
