Unlocking the Secrets of the Puzzle Box &break;&break;Have you ever thought inside the box? These band-sawn boxes could be the most intriguing and fun projects you've ever made. &break;&break;Author Jeff Vollmer describes his boxes as key-and-slide–cut a dovetail key, cut a slider piece, cut another key, cut another slider. That's the puzzle or "combination" you use to get to the chamber or heart of the box. &break;&break;Then you cut out the guts of the box to create a chamber. But wait, there's more! Then you cut another box from the guts, then another box or drawer from those pieces, then another and maybe another until things get too small to handle safely. &break;&break;Any type wood can be used to make these boxes–wood with holes, cracks, splits, insect and wormholes, spalting and burls. Jeff calls these flaws "opportunities" to become creative. &break;&break;Please note that the digital version of this book does not include the accompanying DVD.

The tale begins over three-hundred years ago, when the Fair People—the goblins, fairies, dragons, and other fabled and fantastic creatures of a dozen lands—fled the Old World for the New, seeking haven from the ways of Man. With them came their precious jewels: diamonds, rubies, emeralds, pearls... But then the Fair People vanished, taking with them their twelve fabulous treasures. And they remained hidden until now... Across North America, these twelve treasures, over ten-thousand dollars in precious jewels, are buried. The key to finding each can be found within the twelve full color paintings and verses of The Secret. Yet The Secret is much more than that. At long last, you can learn not only the whereabouts of the Fair People's treasure, but also the modern forms and hiding places of their descendants: the Toll Trolls, Maitre D'eamons, Elf Alphas, Tupperwerewolves, Freudian Sylphs, Culture Vultures, West Ghosts and other delightful creatures in the world around us. The Secret is a field guide to them all. Many "armchair treasure hunt" books have been published over the years, most notably Masquerade (1979) by British artist Kit Williams. Masquerade promised a jewel-encrusted golden hare to the first person to unravel the riddle that Williams cleverly hid in his art. In 1982, while everyone in Britain was still madly digging up hedgerows and pastures in search of the golden hare, The Secret: A Treasure Hunt was published in America. The previous year, author and publisher Byron Preiss had traveled to 12 locations in the continental U.S. (and possibly Canada) to secretly bury a dozen ceramic casques. Each casque contained a small key that could be redeemed for one of 12 jewels Preiss kept in a safe deposit box in New York. The key to finding the casques was to match one of 12 paintings to one of 12 poetic verses, solve the resulting riddle, and start digging. Since 1982, only two of the 12 casques have been recovered. The first was located in Grant Park, Chicago, in 1984 by a group of students. The second was unearthed in 2004 in Cleveland by two members of the Quest4Treasure forum. Preiss was killed in an auto accident in the summer of 2005, but the hunt for his casques continues.

"Of immense interest to those who enjoy recreational maths and puzzles . . . even the most hardened puzzler will find something new." -- Mathematical Gazette Puzzles are as old as history itself, following an arc like that of technology: centuries of slow progress, followed by rapid expansion in the 1800s, and an explosion of activity in the twentieth century. This collection by bestselling author David Wells, a Cambridge math scholar and teacher, follows that pattern. Its first part is devoted to puzzles from ancient Egypt and Babylon and subsequent sources, featuring those devised by Lewis Carroll, Eduard Lucas, Sam Loyd, and other master puzzlers of the Victorian era. The second part demonstrates the tremendous variety of twentieth-century puzzles. More than 560 puzzles are included, from the "mind sharpeners" of a medieval monk to the eighteenth-century Ladies' Diary, the Hindu Bhakshali manuscript, and riddles and popular rhymes. None requires any mathematics beyond the most elementary algebra and geometry -- and few require even that. Complete answers appear at the end.
