Second Monitor Mac Book Pro

Hi,

This is a good fun question!!
I am studying film production and with my course I got a macbook pro, so now i have two!!
As I am using final cut pro a lot, well it would be very useful if I could use a second monitor. I don't really want to buy one so I was wandering if I could use my second mac book as a second monitor!!?? Is there a program out there or a way which allows me to do this?? ;D
I know there are several programs for pc that exist but for mac??

Thanks for some answers

There is some software that can let you do this. However, it can be laggy and useless for movies. Have you thought about selling one?

Agree, you would be much better off to just buy another monitor.
