    You could do multi lines of small led`s and have them run on a chase up and down the screen, could even do muticolour led`s for extra creative looks. The key would be what you use as a cover plate, white acrylic would even out the light.

    Cool, maybe a belt style arrangment with a slit could be an option, will try and think of an item that has that motor style feature.

    Search fingerprint scanner on you tube and you will find countless examples,
    theres even an app that has one, got an old iphone? build a case around it.

    I have a Microsoft keyboard with a built-in fingerprint scanner. When you place your finger on the scanner, the light flashes, to let you know it's been scanned. ANd it actually works - I've had all my family members try to get in to my machine and they can't because of the scanner.

    It's a couple of years old, so maybe you can find one for cheap and scavenge the scanner. The scanner window is about 2"h x 1.5"w.

    Get some footage of one in action, convert the file and transfer it to the nano
    perhaps. Sounds like your gunna be very resticted in a motorised sense with the space you have available.

    Piggy backing off of this, get one of those cheap chinese Video Mp3 players and build a case around that.

    Why not take a cheap keychain laser pointer apart and mount the laser to a small low power motor (like a cheap electric toothbrush)? You would need a filter (lots of laser pointers come with them) that spreads the dot into a line. The gears on a toothbrush are already set up to do a "scan" motion. You just need to slow it down. Perhaps with the addition of the laser consuming some of the power, it will move slow enough to do a quick "scan" pass.

    hmm if thats a good enough motor i can attach a metal plate with a slit in it to get my desired effect... toothbrushes i thought were vibrating motors so set foward and back... just a rumble motor

    That's what I would have said, too. You can get keyfob sized ones from places like Dealextreme for very cheap, and I doubt you'd do it smaller. A bit of fiddling to make it press a key when you push down on it with your finger, and you're done.

    They can be made to look nice with proper installation and diffusion, but there is R&D time that can make the cost skyrocket...

    As others have said a small Asian mp4 player is the easiest solution...

    No endorsement or anything just an example link...
