This is a Dot Matrix Label, It supports color gradients for on and off dots to give it that 3D look. Also uses smoothing to make it look even better. Dot height and width along with the space between dots is customizable. To top it all off, the control is already double buffered, so it will never flicker. This is a great example of drawing and using a data matrix. It redraws quickly.
