This Ultimate Geek Pen incorporates five functions in one slim silver form factor. First it writes as a ballpoint pen, it also has a PDA phone stylus in there, then there’s the green laser pointer, then an LED flashlight and finally a UV counterfeit note lamp for checking your currencies. Warning, this thing will definitely get you bashed about at break time. $9.95.

 This high tech gadget has enough bells and whistles to make most geeks drool. Twist the metal tip one way and you get a ballpoint pen, twist it the other way and you get a stylus tip for use with PDAs and games. Press the top button to turn on the laser pointer, press the bottom button to cycle through the flashlight and UV light.
