Apps :: .pps files

What else can be used to view .pps(power point slides) besides the huge openoffice. I'm looking for something a whole lot lighter to view .pps. Anyone know of any alternative apps?

There's a script used to convert and display ppt files as html. I don't know if that's the same as pps, but it's power point.
