We wanted to use Processing to understand a bit more about what makes this TNTTearDrop shape 'tick.' It's made using parametric equations:

                        x = a * cos(t)
                        y = b * sin(t) * sinm(t/2)
                        

The key players in the equations are:

• t, time
• a and b: scale factors on the x and y variables respectively
• m, a power on a sine factor

The sliders in the control console allow you to see the effect of a, b and m on the figure. The 'hue' slider lets you choose the 'fill' color of the shape.
