Tangram is an old Chinese game of shapes. The goal is to form a particular shape from a set of seven pieces. Although this may sound easy it turns out to be pretty difficult. In the standard game the set of pieces consists of 5 triangles (of three different sizes), a square, and a parallelogram. This program challenges you to solve a huge collection of Tangram puzzles. You are presented with a shape and have to put the different pieces into it, by moving and rotating them.
