This app allows you to create interesting shapes using affine transformation. Affine transformation can do translation, rotation and scaling on object's coordinate. We do iterations, and in each iteration we apply the affine transformation on the object (circle, rectangle, star, polygon or line), coloured in gradient. At the end, you may like the result.
