already thought about this.
When I get a radar detector I will be working on it. But I need a radar dectector with LED's that I can read voltages off for distance and type of signal detected then make mappoint put a drawing on where I think it is, and maybe a speach engine or something.
Im not doing it any time soon, have other stuff to work on, but I thought this would be cool.
Or even just an application that puts a big *** warning on the screen and makes the sound of police sirens would work for me :-P
