Draw a shape by clicking with the mouse one point at a time. When you're done, click on the done button. Then adjust scale and rotation and click on the draw button. Have fun!
This project stores pairs of mouse X and Y values in a list. It then multiplies each pair of points with a 2 by 2 matrix to transform the scale and rotation. Finally, it uses the pen to draw out the points. Note that scale and rotation are percentages: 0 to 100% for scale and 0 to 100% of a turn for rotation.
