A company called ThinkGeek is now selling a aircraft tracking laser. It
hooks up to the internet via a number of sources online to identify
aircraft in the area and then tries to target them. It plugs into your
computers USB port. Not a bad price at that!

That is a good price, I think I'll get one for my son for his birthday. He
loves airplanes!
