The sonic screwdriver from Doctor Who. It should be able to:
-use left click for sonic-ing, right click for scanning
-use the light key to extend/retract (extending gives it more range and power)
-have a power bar that goes down at a slow rate when using the extended mode
-have three input events: OnSonic, OnSonicScan, and OnSonicExtended
I also request that you do either the 10th doctors screwdriver or the 11th doctors screwdriver. Which ever works for you.
EDIT: re-read the thing about modeling. Just use the default printer. It's white and shoots out a blue ray which looks like the 10th doctors screwdriver.
