Does anyone get how these things work?   I usually figure things out without having to read up too much, but I just never have been able to understand how using a regular monitor these things know which pixel you're pointing at..

Also same deal with the light guns, like on the NES.. same deal.. how does it know? Must be the same technology..Seems simular.  

Thanks,
