Forget touch screen, just breathe into it

Imagine being able to switch songs on your iPod by just blowing on your zipper jacket. Or moving a mouse on a computer screen with your telephone headset microphone. These are just a few examples of a new project called SensaWaft that lets you control a computer with your breath.

Zyxio, pronounced "Zick-see-o" (I think), is a Las Vegas-based startup developing the technology.

If you think this is something you want to play with, there is a contest running right now called Be a Mind Blower. There's a nice cash prize involved, and you can sign up to judge the contest if you don't want to build an app.

The possibilities are endless with this new type of gesture. What other ideas or uses can you think of that will benefit from air-flow technologies like this?
