Favorite PowerPoint ADD-IN?

Well, much more than a PowerPoint ADD-IN (although you find it in the AddIn-Tab) is "Print2Flash". Awful Website but a great tool

Forgot to mention this one add-in that I first used this week.  Actually, I had to pay for it to meet an initial deadline.  :(

In a course that I'm working on, I had a 4-section SmartArt pie figure that I animated on the slide to show what topic the course was now going to focus on.

The internal client liked the concept but wanted a 4-piece jig-saw puzzle instead.  (Why do folks like these so much?  The interlocking pieces showing interrelationships?)

Okay, knowing Tom covered this nicely in an old blog post, I started there.  But I wanted the crossword pieces to form a rectangle when all together.

I couldn't find any clip art to piece together, or any other resource, and I didn't have time to do it myself, so I finally found this jigsaw puzzle maker add-in for PowerPoint.  I purchase it and it worked great.  Really simple to use.

(Now here's where someone pipes up and shows something that is free that does the same thing.     )

It easily creates 4, 6, 9, or 16 piece puzzles of on a new, single slide.  I did that for a 4-piece puzzle, resized the pieces; added images as fills and a little shadow, text, and bevel; then added a motion path to one of the pieces; and then animated in a final shape with text.

Here's how it came out.

@Gerry - Do the Add-ins seem to function well when integrated in Articulate also?

So far (with fingers crossed), just fine.
