Perhaps huffing at your computer might get you somewhere if research at the Georgia Institute of Technology comes to fruition. Shwetak Patel and Gregory Abowd from Georgia Tech have published a paper that describes how to use a computer microphone to determine where on a screen a person is blowing. The technique, which they call BLUI for Blowable and Localized User Interaction, can distinguish between the different sounds air makes depending on where the breath is directed. Note: This won't be part of Grow. Just so you know.
