How Can You Use DirectX in a Webpage?

Question

I am trying to figure out how to put even the simplest DirectX application on a web page. I'm trying to use Tutorial 3 from the DirectX SDK. I am using a UserControl object, however I don't know how to, or if you can, use this object in the same way as they use a Windows Form in the tutorial. After all you can't embed a form object in a webpage can you? I put the Main code from the form in the Initialization funciton for the Control, and got rid of code for Esc to exit and on resize and all that, compiled it as a DLL (Windows Class Library). Still I don't know if there is any sort of message loop for UserControls like there is for Forms, or what I would have to do to use DirectX in a webpage period. Maybe there is a way to embed a form in a webpage, or maybe I have to use a UserControl with a timer object or something. If anyone has any suggestions I would like to hear them. It seems to me that you need to use an application to use DirectX, but a UserControl can't be an Application right? I'm sure someone knows what it is I need to know. By the way, the reason I want to embed a DirectX Application in a webpage is because I have written some code to render 3D bitmaps, and I want to make it my desktop background, silly reason I know but they are awesome bitmaps custom 3D iterative fractal density plots that I've made. I might post the results of this if I can ever get it in a webpage!
