MicroArduino Controlling EL Wire with Transistor?

It's pretty much bound to work IMO (you cut the power, how could it keep going? x) - but then again I'm frying MOSFETS like there's no tomorrow so my advices aren't worth much =p ) but what I really wonder is: Can it dim? :3 - flashing it on and off through PWM (I need my EL panel to "heartbeat" in style for a project =) - but i'm too afraid to fry my one and only inverter :<, ebay shipping times are scary..) ... That'd be so badass o_o ......
