The Label control was a bad idea because it changes the behavior of your code. When you set the value of the Text property, the label does not get repainted at that time. It forces the label to Invalidate itself, telling Windows that it needs to repaint. Windows will get around to posting a WM_PAINT message to the applications message queue. When the UI thread finally goes back to idle, the queue will get processed and the paint message makes it way to the label control, telling it that it is now OK to paint itself. That is when the label actually changes on screen.

Moving on, you never use the value of the Random so it's never being painted anywhere.

Form_Paint is a bit much for this. I'd create a Control specifically for the purpose. This makes the code reusable and easily maintained.

The control would have it's own Random, it's own Timer, and a couple of methods to Start and Stop it's behavior.
