OK, what you have downloaded and installed is the Vision Egg library.
What you need to do now is to get the Vision Egg demos. As it says at

Thus, you'll need to download the source code to the VE to get the
demos. You should also be able to get that at SourceForge.
(I wish there was an easier way to do this, but there's no good,
standard way in python do ship a bunch of demo scripts with a library.)
