Tangram - Animals by Pixmaniaque

The tangram is a dissection puzzle consisting of seven flat shapes. The objective of the puzzle is to form a specific shape (given only an outline or silhouette) using all seven pieces, which may not overlap. It is reputed to have been invented in China during the Song Dynasty. A Chinese psychologist has termed the tangram "the earliest psychological test in the world", albeit one made for entertainment rather than analysis. Source : http://en.wikipedia.org/wiki/Tangram
