Generate openscad code for a very beautiful and unique planter. Iterate as many times as possible on the design, looking at the rendering in each iteration and improving it. The goal is to generate a unique and aesthetic planter design amenable for 3D printing.

module unique_planter(
    height = 100,
    width = 50,
    wall_thickness = 4,
    twist = 90,
    freq = 8,
    amp = 2,
    drainage_hole_rad = 5
) {
    $fn=100;
    difference() {
        linear_extrude(height = height, scale = 1.2, twist = twist, slices = 200) {
            polygon([
                for (a = [0:360/$fn:359])
                let (r = width/2 + amp*sin(a*freq) + amp*sin(a*freq/2))
                [r*cos(a), r*sin(a)]
            ]);
        }
        translate([0,0,wall_thickness]) {
            linear_extrude(height = height, scale = 1.2, twist = twist, slices = 200) {
                polygon([
                    for (a = [0:360/$fn:359])
                    let (r = width/2 - wall_thickness + amp*sin(a*freq) + amp*sin(a*freq/2))
