Not sure, but maybe he's referring to the mouse cursor shape that GUIs often use to indicate that something is busy — formerly known as "hour glass" cursor, but having more recently been replaced with all kinds of animated other shapes, in an attempt to make GUIs look more stylish...

Note to the OP: never assume that people can read your mind and automagically will know what you're talking about... The shorter the question, the less context there is, and the more ambiguous terms often are for the reader.
