Animated product customizer for website

My company is looking to redesign our website to include a product customizer. This would be a Flash (or similar) interface that will allow the user to select a base product, then to click buttons to customize the product. For example, a customer may want to change the color of the displayed model, or to view the product with optional accessories. All products displayed should be 3d models. When changes are submitted, the user should see an animation displaying the installation/removal of any accessories. Ideally, the interface should include a method for the user to rotate the 3d model in 3 dimensions and zoom in/out.
