Powerpoint-like program??

[yh125d]

I need to finish a powerpoint presentation, FAST. I have no access to a pc with powerpoint except at school, and once i get there i am supposed to be doing a presentation. I have about 1 1/2 hrs to finish what i have already done. Please, does anyone know of a free/shareware program that can edit and add to existing powerpoint files??

There's OO2.0's implementation, but it's not that great compared to PP itself. You may just be better off doing what way said and getting a trial.
