powerpoint-style transitions with CSS or other simple web answers

Hi folks,

Is there an easy, friendly way to get web-pages to make
visual 
transitions in a fashion similar to PowerPoint
fade/slide/speckle/etc 
transitions?
We're looking at developing a kiosk that would display
weekly campus 
events. The original idea was to create a PPT file every
week, which 
sounds incredibly labor-intensive and boring. I'm thinking
of using a 
PHP/MySQL back-end that will manage the content, but would
still have a 
PowerPoint-like presentation. My mockup relies heavily on
the 
http-equiv=Refresh tag, just loading one event-page after
another.

The PPT-type transitions are certainly non-mandatory, but
sprinkling 
them in gently might create a bit of eye-catchery and visual
appeal. Is 
there a straightforward way of doing this with CSS, AJAX or
something else?

Any ideas?

Thanks
Ken
