Macbook Pro And 2 Monitors, help Options

[evolution]

Hi

How do I get two monitors attached to my macbook pro? yes I could attach 1 and use my laptop screen but I want 2 x 23 inches that I have (lucky i know!) to run off the macbook pro and be able to arrange them so the are not mirrored but showing different stuff. They are currently attached to a g5 tower (since died) that has two connectors but the mbook has only one. I have looked at splitter cables but my impression is that these will only duplicate the same image on each monitor (mirrored)

Any ideas
