Mathematical Heart

Valentines Day is coming up, and you less artistic folk might want to make a nice heart picture to send to your girlfriend. A parametrization of a heart shape is the following: $$x = 16\text{sin}^3(t)$$ $$y = 13\text{cos}(t) - 5\text{cos}(2t) - 2\text{cos}(3t) - \text{cos}(4t)$$ The heart is drawn as $t$ ranges from $0$ to $2\pi$. How you increment $t$ can alter the picture in cool ways. Interestingly, the area enclosed is exactly $180\pi$

Blue, scale = $\frac{3}{2}$,   $t = 1, 2, 3, ...$

Red, scale = 1,    $t = \frac{1}{2}, \frac{2}{2}, \frac{3}{2}, ...$

Black, scale = $\frac{3}{5}$,   $t = \frac{1}{100}, \frac{2}{100}, \frac{3}{100}, ...$
Green, scale = $\frac{1}{5}$,    $t = k(\pi - .01), \; k = 0,1,2, ...$
