Alien Skin Xenofex 2, Effects Plug-in Software for Photoshop, Macintosh & Windows.
Alien-skin Xenofex2
I purchased this software specifically to use the jigsaw puzzle effect for a PowerPoint presentation.  It performed excellent and produced beveled edges on my pieces for a really nice professional effect.  I wasn't sure how to use the software to produce the puzzle when I got it, but received personal instructions from the rep at Alien-Skin (number listed on their website).  Once I knew what I needed to do, it was a snap constructing the puzzle from a picture using Paint Shop Pro 7, and then importing to MS PowerPoint.
