Five noteworthy PowerPoint add-ons

Perspector

Perspector is fun to play with, and I was able to produce a few fairly impressive objects. Some turned out better than others, and I kept getting an error message that seemed to reflect a small code glitch somewhere, at least in the trial version. But it didn't hamper the generation of the images.

Perspector comes in several editions, ranging in price from $ 59 to $299. If you use a lot of charts and business graphics in your presentations -- and you're not content with PowerPoint's built-in options -- a test drive of this add-on might be worth your while.
