Tangrams

The tangram is a combination of plane polygonal pieces such that the edges of the polygons are coincident. There are 13 convex tangrams (where a "convex tangram" is a set of tangram pieces arranged into a convex polygon).

Curiously, a tangram with colored squares (right figure) is part of the logo for the Dynegy company.
