This interactive Java applet allows users to explore tessellations made from quadrilaterals. The user deforms a square into another quadrilateral, which then tiles the plane. The user can choose two colors for the tessellation. An information window provides data about the shape to be tiled, including: area, perimeter, coordinates for vertices, and side lengths.
