Praise Mark Leidner's Twitter account.

That's why this book exists. I followed and really enjoyed his contributions to HTMLGiant for a while — videos like this or this — and then somehow found his Twitter account. Every tweet of his contained something salient, and I'd often stare at some for a long time, figuring and refiguring their beauty, their doomed solutions, on and on.

I eventually realized: this is a book. These aphorisms need to be collected and presented in the form I love to hold. Mark and I worked on the book for a year and a half.

The design of the book seemed self-evident: a dictum: give each truth its deserved space. One aphorism per page. No page numbers. A perfect square, 5x5; five letters in the Sator square, too. The cover is the first idea I had for it; yes, a paradox, but can't we fit most paradoxes into a box?

Following Chris's book is a tough act, but The Angel in The Dream of Our Hangover contains enough wisdom and imaginative leaps, sprent across so many domains, to last a lifetime. I believe that. I love this book.
