Good vibrations

I'm sitting in class the other day and someone's phone starts to vibrate. Ya know, that quiet reminder that everyone in the room can hear. Now I know full well that my phone is turned on silent. But as the vibrating noise is heard for the third time I reach down just to make sure. Open up my phone carrier thing on my Timbuk2 bag, and nope, not me. But right when I reach down the noise stops. The teacher looks at me. What!? seriously man it wasn't me!! So now I'm trying to find a pencil or pen or something I can pull from my bag to say, "see... here! that's what I was reaching for, not my phone!". But I got nothing, so I go up empty handed, taking the blame for the phone noise. That got me thinking.

We have custom ringtones. Why not custom vibrators? Now I know the ladies out there are saying, "hell yea!! I want some custom vibrating action." But seriously. If you could also program your phone to tap out some simple rhythm, then you'd know if its your phone right away. Now certainly this wouldn't matter if you had the phone in a pocket, as you'd feel it right away, but with everyone putting phones in bags and stuff, it's really hard to tell who is vibrating and who isn't. So here is my challenge to the cell phone companies out there: get me a phone with some customizable vibration action.
