Some of us see the world in a different way. I'm talking about people who can look at a skyscraper and see all the angles within it, considering the layers of materials that went into those floors and how they line up with each other. It's people who have an uncanny ability to navigate to and from a new destination by barely looking at a map. These are the spatially intelligent humans who thrive on tangrams, nonograms or any other spatial reasoning puzzles. If you've made it this far and you are still interested, this book may just be the challenge you are looking for. Buried in these pages are specific technical artistry challenges that will push you to consider the very formation of the lines and shapes we take for granted. You will be allowed only a ruler and pencil for the following challenges. The whole point is for these tasks to be a bit grueling at times, but the true difficulty is in the meticulous execution of the requirements and the rewards for creating a perfect product. Call it a set of geometry challenges if you will, this book offers 30 specific drawing challenges split up into five sections covering 2-D and 3-D tasks as well as the art of illusion. Nestled in the back of the book, you will find a section for hints at how to conquer each challenge and full step-by-step solutions with diagrams. This book was created for people who think a bit differently. If you consider yourself spatially intelligent and love a good challenge, this is definitely your next project.
