    One way to distinguish the ways we DO things is with HANDLES or BUTTONS.
    Buttons are discrete, handles continuous. With a button you initiate and let go; with a handle you grab on and contol.
    Button clicks are more likely symbolic - we string them together. Handles are more analogic - we gesture and indicate.

    Bring to class two sketches (8-1/2 x 11) one of a "handle" one of a "button".

    Sketch enough of the context so it is clear where and who might use it.
    List the features that make this a good or bad example -- what you like or don't.
