Math Wonderland is a museum of interactive mathematical models in Hokkaido, Japan. This book presents mathematics and models: reversible solids, plane tiling with developments of tetrahedrons, and double-packable solids. It aims to entertain, inform and even teach some mathematics.

This book constitutes the thoroughly refereed post-conference proceedings of the China-Japan Joint Conference on Computational Geometry, Graphs and Applications, CGGA 2010, held in Dalian, China, in November 2010. The 23 revised full papers presented were carefully selected during two rounds of reviewing and improvement from numerous submissions. All aspects of computational and discrete geometry, graph theory, graph algorithms, and their applications are covered.
