In some past projects I have ended up implementing a few controls notably absent in the framework, such as a basic flowchart. Initially, these controls ate way too many cycles when interacting with them (dragging around flowchart boxes for example) -- I eventually discovered that it is a good deal more efficient to only redraw the invalidated regions and in some cases to cache parts of the control as bitmaps in memory.

I'm sure others have toyed with the drawing facilities available in .Net at some point, be it for simple games or any variety of control.
-What do you do for optimization?
-What CPU/Memory utilization do you typically see?
-Do you use the anti-aliasing or compositing features?
-Have you created any interesting controls that you are want to demonstrate?
-etc.
