Mike M's Loop du Jour:

This space curve was produced using the following Maple commands:

> x:=cos(t);
> y:=sin(t);
> z:=sin(cos(t/4));

                             x := cos(t)


                             y := sin(t)


                         z := sin(cos(1/4 t))

> with(plots):
> spacecurve([x,y,z],t=0..8*Pi,thickness=2,
>   numpoints=1000,axes='FRAMED',orientation=[115,85]);
