Although you could consider them a presentation cliché, puzzles can work really well in a presentation:
- Show how things fit beautifully
- Show how your are missing (hopefully just one) critical piece
- Show that you finally managed to plug that last gap
Puzzle shapes can also work great when you use them in combination with images. You can go back to this blog post about making Photoshop-like image cut outs in PowerPoint.
Stock image sites are flooded with millions of puzzle piece designs, but they are not very practical for the average PowerPoint designer (especially late at night working for tomorrow's deadline). Almost all these puzzles pieces are vector objects or images that are impossible to edit in PowerPoint. Moreover, all these puzzle pieces have wildly irregular shapes that make them hard to fit in your slide composition that requires exactly nine of them.
This PowerPoint puzzle slide solves the problem for you. The pieces inside are fully editable PowerPoint shapes, you can change their colour, you can put text in them, you can reconfigure and piece them together as you see fit. Yo'u can download the finished slide by clicking the image (An Apple Keynote version is available as well).
You can try to create the pieces yourself if you want, I used simple square shapes and circles, either joining or subtracting the shapes. Circles and squares might not be the most realistic shapes, but they are very practical when have to piece things together. There is a little bit of math homework to do to determine which type of puzzle shapes you actually need, and which ones you can create by rotating existing pieces.
