Reegan's Bent Spiral:

This space curve was produced using the following Maple commands:

> x:=sin(sin(t));
> y:=sin(cos(t));
> z:=t;

                           x := sin(sin(t))


                           y := sin(cos(t))


                                z := t

> with(plots):
> spacecurve([x,y,z],t=0..8*Pi,numpoints=1000,
>   orientation=[20,80],thickness=2,axes='NORMAL');
