To get those light trail shots you really need to have a Digital SLR Camera.
I have loads at home, just dont have any net acces to upload them. They are quite easy to do, but you need a tripod.
The idea behind them is that you set the camera to leave the lense open for a set length of time, ie 3 sec or 30 sec. What happens is that due to the lense been left open for this time and light that is around is caught on the sensor, but when the light source is moving you will see the trail moving and the subject will be very faint.
