Why is one front light blue and the other isn't? :/ Nice screen, but I don't think it looks really realistic, the car I meant. :/ But it looks somehow reallistic...
If you meant what program is used to take screenshots! Then there is Fraps. There are others which I don't know...You can also take pics with "Print Screen" button on your keyboard.
