Reloj Analógico en WPF y C#

Un código matemático para dibujar un reloj analógico. Lo hice en WPF sobre un Canvas, pero puede dibujarse sobre cualquier contenedor:

<Canvas Name="ClockContainer" Height="200" Width="200" />

public void DrawClock(double centerX, double centerY, double width)
{
    double radius = width / 2;

    // Border.
    Ellipse ellipse = new Ellipse()
    {
        Stroke = Brushes.Navy,
        StrokeThickness = 2,
        Width = width,
        Height = width
    };
    Canvas.SetLeft(ellipse, centerX - (ellipse.Width / 2));
    Canvas.SetTop(ellipse, centerY - (ellipse.Height / 2));
    ClockContainer.Children.Add(ellipse);

    // Center.
    ellipse = new Ellipse()
    {
        Stroke = Brushes.Navy,
        StrokeThickness = 2,
        Width = 4,
        Height = 4
    };
    Canvas.SetLeft(ellipse, centerX - (ellipse.Width / 2));
    Canvas.SetTop(ellipse, centerY - (ellipse.Height / 2));
    ClockContainer.Children.Add(ellipse);

    // Ticks.
    for (int i = 0; i < 60; i++)
    {
        if (i % 5 == 0) // 5 minutes tick is different.
        {
            Line line = new Line();
            line.Stroke = System.Windows.Media.Brushes.DodgerBlue;
            line.StrokeThickness = 2;
            line.X1 = centerX + (radius / 1.10 * Math.Sin(i * 6 * Math.PI / 180));
            line.Y1 = centerY - (radius / 1.10 * Math.Cos(i * 6 * Math.PI / 180));
            line.X2 = centerX + (radius / 1.25 * Math.Sin(i * 6 * Math.PI / 180));
            line.Y2 = centerY - (radius / 1.25 * Math.Cos(i * 6 * Math.PI / 180));
            ClockContainer.Children.Add(line);
        }
        else
        {
            Line line = new Line();
            line.Stroke = System.Windows.Media.Brushes.DodgerBlue;
            line.StrokeThickness = 1;
            line.X1 = centerX + (radius / 1.10F * Math.Sin(i * 6 * Math.PI / 180));
            line.Y1 = centerY - (radius / 1.10F * Math.Cos(i * 6 * Math.PI / 180));
            line.X2 = centerX + (radius / 1.15F * Math.Sin(i * 6 * Math.PI / 180));
            line.Y2 = centerY - (radius / 1.15F * Math.Cos(i * 6 * Math.PI / 180));
            ClockContainer.Children.Add(line);
        }
    }
}
