Im currently working on a portable n64 and uh...I was just curious as to how many of you think it would be "nifty" to have a built-in rumble pack, BUT the motor from it was removed and replaced with a light circuit to make lights (LED's or a couple small cathode tubes) flash instead of making the motor rumble.
Sound original? I hope so because I'm really trying to steer away from the "What-has-been-done-before" ideas and I thought it sounded fun.
Picture this - Your playing Goldeneye or Quake and everytime you shoot, your portable flashes....ooooo

....wow. Or playing MarioKart and when you hit a wall, your n64 lights up....ahhh

...neato....
Anyway, question number A -- Has this been done before?
And question letter 2 -- Does it sound cool

or just stupid?
