You can use all the prefab custom animation in Impress. However, you can also control that path that an object takes. For instance, if you have a diagram and you want a small electron object to follow a certain path through the diagram, you can use OpenOffice Impress to do that.
Here's how it works.
Draw an object, then under Custom Animation’s Motion Paths tab, select any one of the first three effects.
Your
cursor will change so that it will draw the kind of line you
selected. Draw the path that you want the object to follow. Then run
the presentation to see the effect.
To
edit existing motion paths, just apply a standard motion path like
Eight-Point Star or Diamond. The path will appear in the slide.
Click on the path and expand it; you’ll get another path (there’ll
be two diamonds, for instance). Delete the old path, and you’re
good.
