Green flag. In automatic mode, will automatically morph from one shape to another random one. Press space to toggle manual mode, where you can control the next shape using the number keys : 1 - Circle 2 - Square 3 - Triangle 4 - Heart 5 - Star 6 - Trapezoid (thank you @superdude1234567 for suggesting it) 7 - Hexagon(thanks to @Dookler ) 8 - Deltoid (thanks to @qwertyman5 )
Now I can actually see how the transformation occurs, and which point goes where. I also decreased the dot size.
