Instructables
Motion tracking done with a webcam and some Lego
This is just a very crude design (especially the hardware), but you can apply the things you learn here to a more polish and solid setup too. You can also add a gun/rocket launcher/cannon as many of you would think about it

For this project the main things i used is a webcam, 2 NXT motors and an NXT "brick"
the software used is Roborealm (I am using their 30 day trial) with a custom VBscript

I learned of the software from this video and the VBscript is a modified version of the one he provided, so credits to him

Very nice project. Could definitely be used in some sort of security system for home automation!
