1. Click on the “Green flag”: everything is reset to original state. 2. Select a design by clicking on one of the buttons. 3. Enter inputs if prompted and watch the design. 4. For some of these designs (e.g. the spiral) you may want to use “Turbo mode”.
This is a program in which we will draw a few interesting “recursive” designs. A number of buttons (with names of designs as labels) are lined up along one edge of the screen. When you click any of them, a design is drawn on the screen. You can control the resulting design by entering some inputs, such as, size or angle of a shape, or the depth of recursion.
