Scrolling numbers like a mechanical counter?

Question

What is the recommended way to create large scrolling numbers with C# and Visual Studio .Net? I want the numbers to appear to be rolling on a continuous mechanical drum. For example, if the number to be displayed is 18.65, the display area would show half of the 6 and a 7 because of the 5 in the hundreths position. I have been playing with the LinearGradientBrush to make the numbers appear to be turning on a round drum by starting with a light color in the middle of the display area and the color becoming progessively darker toward the top and bottom of the display area. Any C# .Net examples of this available?
