Lighting Diagrams

[Mojo Jojo]

Now i'm doing alot more studio work, i think it would be a darn good idea to be able to make lighting diagrams of what i want to achieve.
Does anyone know of any real easy way to go about creating them? (digitally).
Any specific software (preferably free or cheap, we all want something for nothing these days and i'm afraid i'm no exception)
