There are so many great, hidden (or at least not as known) functions in PowerPoint. Without even leaving PowerPoint you can add great effects to your slides.
Jim Lerman's insight:
A nice technique, but be careful. It doesn't always add to the slide, as the title slide in the post so clearly demonstrates. If the background is too busy, as it is here, viewers can't read the text.
