Finding the "perfect fit"
Here's an idea (and a download with the graphics and an animated example) for you to illustrate "matching," "perfect fit," and "completion" concepts. They work well with animation (see the video and the animated example to see how you might animate the slide).
The bottom half of the objects contain an imported empty desk photograph. The top half of the objects contain photographs of the successful applicants. You can, of course, use the graphics in other ways. For example, the download also contains objects that have been split in half vertically, so you can type text in a rectangle, save it as a picture, and then import the cropped picture into the two halves. Then when the to halves align, the word or phrase is complete and readable.
Have fun with this one. It's unique and worth the small amount of effort to create a memorable slide.
