Using the Vortex

This graphic can be used as a whirlpool (objects enter from the top and go down into the vortex) or as a tornado (objects enter from the bottom and go up into the vortex). Either way, this conceptual force is powerful and uncontrollable.

Customizing the Vortex

Adjust size

There are two pieces of of the vortex: the front and the back. Both are semitransparent so objects within and behind the vortex can be seen. It's important to keep these two pieces exactly the same size.

Color variations

The graphic is a PNG. It can be tinted in PowerPoint 2007, but cannot be modified in PowerPoint 2003 other than brightness and contrast (as with a photograph). The download for this series has two variations of the vortex. One is as was drawn by the artist and the other has been tinted gray in PowerPoint 2007. Both are semitransparent.

3D variations

Don't apply 3D to the vortex.


Don't apply shadows to the vortex.

Gradients, patterns, and pictures

Don't apply any of these effects to the vortex.


Objects can be animated to go into/out of the vortex, but the vortex cannot be animated other than to move horizontally across the page. Since it cannot be animated to undulate, it's probably best to not animate the vortex at all. Animation should be restricted to the objects going into and out of the vortex.
