You've had a chance to try out some of the Paint Effects features and create some complex scenes with relatively little effort. Some of the methods you've learned include the following:
Preparing objects for Paint Effects You can't paint on an object unless it's a NURBS object and has been made paintable during the current Maya session.
Browsing and choosing a brush Maya offers a wide collection of brush presets in the Visor.
Editing brush settings You learned how to change the way a brush paints and modify the stroke's look after painting it.
Saving your presets You can create brushes and add them to the Shelf or a Visor folder for later use.
