This book is really rad. It goes a step beyond the mindless (sorry, I mean mindful) coloring-to-zone-out trend—it engages different parts of your brain with hands-on math concepts. Sure, it's meditative to color patterns, but WHY is that? Color this book, and you'll get a more hands-on understanding of the elegant ideas behind mathematics. Math is not just about numbers, it's about relationships, patterns, dimension, and symmetry. I think this coloring book could actually make you smarter, or at least a little more in awe of the universe and a little less intimidated by math. Math through art! Art through math! Non-dorky coloring for nerds of all ages!
