Book excerpt: Spiroglyphics are a totally original idea from the twisted mind of genius puzzle-designer Thomas Pavitte! Thomas's unique talent is creating activity puzzles that result in something truly extraordinary. His 1000 Dot-to-Dot books and Querkles colouring books have become international best-sellers, enjoyed by creative puzzle fans the world over, with millions of copies in print. Spiroglyphics are even more incredible than anything he has done before. Each oversized design starts life as a featureless spiral, but as you fill in the lines you find yourself creating a surprising, eye-popping portrait of a rock icon. Fun to create and amazing to look at, the Spiroglyphics will blow your mind, and make amazing artworks for your wall!
