A surrealistic thing: this looks like a star.

init

n=k0*600; tpi=2*acos(-1);

point

d=k1*v+i*tpi; x=x0+pow(cos(d),3)*kx; y=y0+pow(sin(d),3)*ky;

k0, k1, kx, ky, x0, y0 are optional values, they equal to 0 (x0, y0) or 1 (k) by default;

If this is well-known, I post it for reference.

This is a bit oldschool, isn't it?

Thanks
