A rails-based web server provide a iPhone UI, through which you can remote control shows of MS powerpoint slides.

My Environment: 1) Window XP SP2, 2) PowerPoint 2003, 3) Rails 2.1, 4) iPhone 2.0

If you're RoR (ruby on rails) developer, just checkout the trunk and "script/server" it. Otherwise, you should install RoR first.

After that, use your iphone visit the site (maybe open some ppts first), and enjoy yourself.

Tips:

• Click the big powerpoint logo to run slides show.
• Move your finger in the direction shown by the green arrow to next slide, and opposite direction to previous slide
