Random Motion tutorial question

Hi.

Here is the link to this tutorial I have a question about:

http://www.kirupa.com/developer/actionscript/random_motion.htm

As you can see objects (flowers) in this example are moving only in straight lines.

Is it possible to make them move also in elliptic lines? (i hope you know what i mean, my english is not too good)

thanks!
