S5: A Simple Standards-Based Slide Show System is a weird thing. It's like Powerpoint for your browser, but it looks like you need to be a .css hacker to really be able to put the thing to good use.

Still, it's a nice alternative to simply putting a.ppt file up, but perhaps it doesn't win against saving your powerpoint/keynote file as a PDF.

Not sure. I'd say that I would play with it, but I'm not sure I will. I like nice smooth fade transitions, cause I'm st00pid like that.
