Using Eris as a secondary laptop monitor

I have the need to use my laptop to show customers Power Point presentations.  When I do the laptop screen is aimed at the cusstomer and I can't see it.  Is there a way to use my Eris as a secondary monitor so I can view my presentations as I'm presenting

You beat me to it jdog.  PhoneMyPc works wonders and is a great program to use for this kind of thing.  Here is a link I found that explains it better.

What can I do with PhoneMyPC?

Take a snapshot of what’s on your PC (check up on your teenager). Show your presentation on a big screen using your phone as a wireless mouse and keyboard. Provide remote support from anywhere. Work on your PC from your phone at the beach. All of this with a trivial setup. And these are the just the basic features!

Thank everyone for the help on this.  I looked into the app that was suggested but the problem is the requirement for an internet connection, which is not always available where I need to prsent my Power Points.  The ideal solution would be an app that uses the USB on the Eris to just show the screens on the laptop.  Being able to control the laptop is not a requirement.  Thank You.
