I am filling the store with presentation essentials. Falling domino pieces might be a cliche, but they become useful if you can actually put text on the stones, rather than simply putting a cheesy stock image as a background.
Below is a downloadable dominoes template in PowerPoint. The pieces are editable rectangular PowerPoint shapes that have been tilted in 3D. You can change the number you want, their colour, and the text inside. I have put supporting 3D lines in the composition so you can clean up things after you made the adjustments to the diagram for your specific situation.
