One of the cooler “eye-candy” type effects possible with WPF is the ability to create reflections. Reflections can be made of pretty much anything and are relatively simple to create. There is a good tutorial on creating reflections using Visual Studio and Microsoft Expression Blend.
The drawback to creating reflections is that you have to repeat the steps for every reflection. Fortunately, one of the developers at Infragistics has created a custom control that allows you to easily create reflections. I have used this control… it works reasonably well and sure beats doing the reflections by hand.
