rumble / vibration

is there a module or something that vibrates or causes rumble.. like an xbox controller? not looking for a sensor, but something that actually does it...

A vibrating motor?
Or a surface transducer (contact speaker)?
Leo..

I don't have an Xbox but the Internet tells me it has a vibration motor. Cell phone vibrators also use a vibration motor, but I assume the motor in a phone is smaller.

A vibration motor is simply a DC motor with an off-center weight.

Horrible things. I ripped them out of my PS2 controller. I don't like the feel of them. The added bonus is that the controller is much lighter now, too.
