Another parametric functions. Inspired from plot#111 idea: stacking multiple parametric functions. The parametric used is

```
let parametric = |t, p| {
(
(0.2 + 0.7 * p) * (2. * PI * t).sin()
+ 0.1 * (14. * PI * t).sin(),
(0.2 + 0.8 * p) * (2. * PI * t).cos()
+ 0.2 * (20. * PI * t).cos(),
)
};
```
