Using the Eruption/Launch
These eruption/launch frameworks can be applied to several concepts: they can be used to show a type of flow, a burst, an unplanned or planned event, a fountain of ideas, and more. The eruption/launch elements are stylistic variations of from 1 to 10 segments.
The source can either be a volcano, which indicates an unplanned event) or a barrel (which indicates a planned or staged event. You can replace the volcano or barrel with your company's logo to indicate a product launch if you wish. You can also use other source points that better suit your message.
Customizing the Eruption/Launch
If you want to change the size/shape of the frameworks, be sure to group it and resize the entire group. Once resized, ungroup to proceed with other customizations.
All of the segments can receive line and fill colors. If the segments are going to appear as the same color, use a gradient and a distinct line color to make sure the individual flows appear separate.
Don't apply 3D to these frameworks. At least do not apply a 3D effect with hard edges. If you're using PowerPoint 2007, you might consider a bevel without a light source so the flows don't appear to be hard surfaces. You can try variations of the bevels. You may just want to apply a gradient to give it volume (see below).
Shadows will flatten the flows and make them look fake. Don't use shadows.
Gradients, patterns, and pictures
A gradient can be used to provide volume if you wish. Consider placing soft-edged photographs in the flows.
There's no real good method of animating these flows to spring from the volcano or the barrel. It's better just to show them as a static graphic.
