One of these books would have a life expectancy of approximately five minutes in my hands - and that long only because the one in the video is almost too beautiful to disassemble and analyze.

Almost.

If you rotate the trick 90 degrees, you get the basis of the Rubik's Magic toy/puzzle.

Here is a square quatragon book.

My favorite bookbinding video right now is The Complex of All of These. Almost makes me want to do edition work.

Abi @ #10: Sprint (the cell service provider) used the square quatragon format for one of its promotional mailings awhile back. Huh...quite awhile back -- there's a 2005 copyright notice on it. Most direct mail ends up in my recycling box. Some ends up in my "good example/bad example" files. This one earned a spot on top of my supplies bureau 'cause the design is just that clever.

These are very cool, but I'm not allowed to buy new blank books until I use the ones I've got.

(and oh, drat, it looks like Hill House is no more)

Yes, I do. Have many, many pretty blank books. I go to an annual conference where they hand out pretty spiral bound books with pretty logos. You're supposed to write conference notes on them. Pfft. I take a regular writing tablet -- last time I just took my Aspire One -- and keep the pretty notebooks for other more interesting things.

I miss Kate's Paperie. That's the place I learned that other people share my obsession.

You could work both socks at the same time on dpns, though I'd think it unwieldy. Still, I think magic loop's unwieldy, too, so I'm not the person to ask. :)

Teresa, you are a wicked, wicked, wonderful woman.

From the video, it seems that the book can have three different covers - black, red and green in the vid. No?

It's basically a toe-up whirlpool toe. Since you can't start from nothing, you cast on 6 stitches (3 for each side). Then knit one round holding the tail end along with the working yarn. Next round, knit each loop as a separate stitch, which doubles your stitch count instantly and gives a more reasonable 12 stitches from which to begin whirlpool increases. Genius! Can't think why I'd never seen it before.

Really nifty find!

The infinite number of covers will be available in their Borges model, out next year. (However, all the pages will have only a single side, making it impossible to read back-to-front or turn back to an already read page, much like life.)

No live organism can continue for long to exist sanely under conditions of absolute reality; even larks and katydids are supposed, by some, to dream. Hill House, not sane, stood by itself against its hills, holding darkness within; it had stood so for eighty years and might stand for eighty more.
…
Within, its walls continued upright, bricks met neatly, floors were firm, and doors were sensibly shut; silence lay steadily against the wood and stone of Hill House, and whatever walked there, walked alone.

First and last paragraphs of The Haunting of Hill House, by Shirley Jackson

Yes, a couple of those transitions were close enough to be almost invisible; I had to look very closely to convince myself there were multiple books, each with only 2 covers.

That being said, I can't visualize the design well enough to say for sure that more than 2 covers isn't possible. I would like it to be possible; I really like the idea of a commonplace book with multiple sections for different topics, each with its own cover.

(or at least delete their link)

Thankee!
